What volume of sulfuric acid solution with a mass fraction of 0.911 and a density of 1.82 gml should be taken to prepare 200 g of a 10 percent sulfuric acid solution.
Let’s find the masses of the constituent components of the solution.
This requires multiplying their mass fraction by the weight of the solution.
Determine the weight of pure sulfuric acid.
M of pure acid = 200 x 0.1 = 20 grams;
In order to find the volume of a sulfuric acid solution with such an acid weight, it is necessary to divide this acid weight by its concentration and density.
The volume of the sulfuric acid solution will be:
V sulfuric acid solution = 20 / 0.911 / 1.82 = 12.063 ml;
The weight of the water will be:
M water = 200 x 0.9 = 180 grams;
M solution = M acid + M water = 20 + 180 = 200 grams;
