Determine the required amount of a substance for preparing a solution.
To do this, multiply the volume of the solution by its molar concentration.
In order to prepare such a solution, it is necessary to weigh and dissolve 1.5 x 0.3 = 0.45 mol of acid in water.
Let’s calculate the required weight of the acid.
To do this, we multiply the molar weight of the acid by the chemical amount of the substance.
M H2SO4 = 2 + 32 + 16 x 4 = 98 grams / mol;
m H2SO4 = 98 x 0.45 = 44.1 grams;
