A glass bottle with a mass of 0.25kg and a mass of 1.5kg when filled with water, then the volume of the glass bottle is m3. It can hold at most - kg alcohol
1.128kg alcohol at most
A container can hold 500g alcohol at most. Now it needs to hold 2.25kg of certain liquid with density of 0.9x10 cubic kg / m. how many containers do you need at least?
A. 3 b.4 C.5 d.6
What is the reason?
The reason for choosing B is as follows: (/ means divided by, * times, ^ power) the liquid volume = mass / density = 2.25kg/0.9 * 10 ^ 3 = 2.5 * 10 ^ - 3 (the negative third power of 10) because it can hold 500g alcohol at most, the container volume = alcohol volume = alcohol mass / alcohol density = 0.5kg/0.8 * 10 ^ 3 = 0.625 * 10 ^ - 3 liquid volume /
Seawater, pure water, alcohol, gasoline, who has the highest density,
Sea water
