Answer:
a. 497g H2SO4.
b. 124g HNO3
Explanation:
Molality, m, is an unit of concentration defined as the moles of solute per kg of solvent.
a. The moles of solute, H2SO4 are:
1.16kg * (4.37mol / kg) = 5.07 moles H2SO4
Mass -Molar mass H2SO4: 98g/mol-
5.07 moles H2SO4 * (98g / mol) = 497g H2SO4
b. The moles of solute, HNO3 are:
1.97kg * (1.00mol / kg) = 1.97 moles HNO3
Mass -Molar mass HNO3: 63.01g/mol-
1.97 moles HNO3 * (63.01g / mol) = 124g HNO3
