September 29, 2021
n (H2SO4) = 1.5 mol.
Let’s determine the mass of sulfuric acid. For this we use the following formula. We write down the solution.
n = m / M.
Where n is the amount of substance.
M is the molar mass.
m is the mass of the substance.
M (H2SO4) = 1 * 2 + 32 + 16 * 4 = 2 + 32 + 64 = 98 g / mol.
m = n * M = 1.5 * 98 = 147 g.
This means that the mass of 1.5 mol of a substance is 147 grams.
Answer: the mass of sulfuric acid is 147 grams.
