1. The answer to what question is 200?
•If the question is to find the % by mass, then
(50.0mL)(1.00g/mL) = 50.0g H2O, and
mass% = (100)[10.0g / (10.0g + 50.0g)] = 16.67%
•If the question is to find the grams/liter, then
[(10.0g)/(50.0mL)](1000mL/L) = 200 g/L
•If the question is to find the # of moles / L, then divide the previous answer by the molar mass of H2SO4.
