When a mole of sodium and a mole of aluminum are put into m g of sufficient water, the density of the solution is d g / cm3, and the percent capacity of the solution is 0___

When a mole of sodium and a mole of aluminum are put into m g of sufficient water, the density of the solution is d g / cm3, and the percent capacity of the solution is 0___

Na+Al+2H2O===NaAlO2+2H2
23------------82------4
23a------------x------y
x==82a
y==4a
Percentage concentration: 82a / (23a + 27a + m-4a)

Under the standard condition, VL gas (molar mass is mg * mol) is dissolved in 0.1L water, and the density of the solution is DG * ml

W%=M*(V/22.4)/[M*(V/22.4)+100]
c=1000dW%/M

Under the standard condition, what is the concentration of the substance in the solution when V L of a gas is dissolved in 0.1 l of water and the density of the solution is dg / ml?

Under the standard condition, W G gas (molar mass is mg | mol) is dissolved in 1 L water, and the density of the solution is DG | ml, then the concentration of the substance in the solution is
A.1000wd\M(w+1000)
B.wd\Mw+1000
C.w\d
D.1000wd\wM+1000

The volume of solute is w / M mole. The volume of solution is calculated by dividing the mass of solution by the density of solution. The volume of solute plus the volume of solvent is not equal to the volume of solution. The mass of solute plus the mass of solvent is equal to the mass of solution
