In order to solve this question, we will use the Molarity formula, which is:
M = n/V
Where:
M = molarity
n = number of moles
V = volume in liters
We don't have the number of moles, but we have the formula for molarity to help us find it, now we add the values into the formula:
3.50 = n/1.00
n = 3.50 moles of H2SO4
Now we have the number of moles, and the molar mass for H2SO4 is 98.079g/mol, now we can find the mass in grams:
98.079g = 1 mol
x grams = 3.50 moles
x = 343.3 grams of H2SO4
