Question
The molecular weight of sulfuric acid (H2SO4) is 98.086g/mol. What is the mass, in grams, of 0.623 moles of sulfuric acid?Express the answer to 3 significant figures.
Solution
To find the mass of the sulfuric acid, you need to multiply the given moles by the molecular weight of sulfuric acid.
Step 1: Identify the given values. Moles of sulfuric acid = 0.623 moles Molecular weight of sulfuric acid = 98.086 g/mol
Step 2: Use the formula to calculate the mass. Mass = Moles * Molecular weight
Step 3: Substitute the given values into the formula. Mass = 0.623 moles * 98.086 g/mol
Step 4: Calculate the mass. Mass = 61.1 g
So, the mass of 0.623 moles of sulfuric acid is 61.1 grams.
