What's the meaning of ml / dl? How to read it? What's the difference between ml / dl and Mg / dl
Milliliter = milliliter
Deciliter = liter
Mg / dl is what unit, how to read, best with phonetic
Medical unit, or chemical unit. Who can introduce it carefully
Mg / dl
Mg of solute per 100 ml solution
Conversion formula of mol / L and Mg / L!
I use the soil fertility meter to measure the K ion concentration is 4.331mol/l. The P ion concentration is 3.615mol/l. How to convert it into mg / L? What is the value? Please include the calculation process
K:4.331mol/L=4.331*39g/L=168.909g/L=168909mg/L
P:3.615mol/L=3.615*31g/L=112.065g/L=112065mg/L
How to convert mmol / L to mg / dl
The molecular weight was 1803.61mmol/l and 6.111mmol/l respectively
3.61mmol/l
3.61*180/1000=0.6498mg/dL
6.111mmol/l
6.111*180/1000=1.09998mg/dL
I wish you success!
How to convert mmol / L and Mg / L?
Because:
Mass (m) = mass of substance (n) * molar mass (m)
therefore
1（mmol / L）= M * mg/L
Take Ca2 + as an example,
If the mass of 1 mmol Ca2 + is 40 mg, the relationship between them is 1 mmol / L = 40 mg / L
I don't understand hi
mmol/L = mg/dl
What's on the blood report,
88 mmol / L cholesterol = how much mg / dl
0.86 mmol / L triglyceride = how much mg / dl
0.83 mmol / L HDL = how much mg / dl
1.66 mmol / L LDL = how many mg / dl

According to the formula of G = mg, P = f / s, the pressure of a uniform cylinder resting on a horizontal table is p = pGH
Calculation formula P = f / s, P = pGH, meaning of each letter
F = PS letter meaning. Just answer. Supplementary pull. I need it urgently
P Pressure f pressure s stress area
P liquid pressure ρ liquid density G is a constant, which is 9.8n/kg (generally approximate to 10N / kg) H liquid depth
F = PS and P = f / s have the same meaning. F = PS is just another way to write P = f / s
understand?
Can g = Mg (g = 9.8N / kg) be used to calculate the gravity of the earth? Why?
Of course not! When we calculate g = 9.8, we calculate the value on the surface of the earth, and the value is different at different latitudes of the earth, let alone in the interior of the earth?
Calculate the mass of the earth, you can calculate by gravity!
What does g = 9.8n/kg mean in physics
G represents the ratio of the gravity of an object to its mass. That is to say, if an object weighs 1kg, its gravity is 9.8N

- 4. When measuring the density of a small solid object, a physics interest group adopted the following experimental operations: first, the mass mo of the object was measured with a balance; then, a certain amount of water was put into a small beaker, and the total mass M1 of the beaker and water was measured with a balance; then, after the object was tied up with a thin line, the mass M1 of the beaker and water was measured, The object is immersed in the water of the beaker (the water does not overflow and the object does not touch the beaker) by holding a thin line in hand. At this time, the measured value of the balance is m2, as shown in Figure 6 A. The buoyancy of an object in water is MOG B. The buoyancy of an object in water is (m2-ml) g C. The density of the object is Mo / m2-m1 * P water D. The density of the object is Mo / m2-m0 * P water 、 I don't understand at all. I'm going to take the senior high school entrance examination right away. It's really disturbing that I don't understand

- 6. A course of junior high school physics [pressure and buoyancy], This is the physical simulation of Haidian District in Beijing in 2009 As shown in the figure (a cylindrical container contains a plastic box, in which an iron block floats on the water surface), the cylindrical container with bottom area S1 contains liquid with unknown density. Put a cube metal block with density ρ into the rectangular plastic box with bottom area S2 (the thickness of the plastic box can be ignored), The plastic box floats on the liquid surface (the liquid will not overflow the container), and its immersion depth is H1. If the metal block is taken out of the plastic box, it is tied under the plastic box with thin wire, and put into the liquid, the metal block does not contact the container, and the immersion depth of the plastic box is H2. Cut the thin wire, the metal block will sink to the bottom of the container, and the plastic box floats on the liquid surface, The depth of immersion is H3. If the plastic box is always upright without inclination, the pressure of the liquid on the bottom of the cylindrical container is reduced before and after the thin line is cut? Two supplementary points: 1. The density of the liquid in the container is unknown, and the expression should not contain ρ liquid. 2. The question is how much pressure has been reduced. Not why.
