2. How many moles are in 35.0 g of dinitrogen oxide?
A) Calculate the mass, in grams, in 2.28 moles of each of the following: Cd, SO3, C5H10O5, Ba(HCO3)2, SF6.
i) Cd
Atomic mass of Cd = 112.411 g/mol
Mass in grams in 2.28 moles of Cd = 112.411 g/mol x 2.28 moles = 256.29 g
ii) SO3
Molar mass of SO3 = 80.066 g/mol
Mass in grams in 2.28 moles of SO3 = 80.066 g/mol x 2.28 moles = 182.55 g
ii) C5H10O5
Molar mass of C5H10O5 = 150.13 g/mol
Mass in grams in 2.28 moles of C5H10O5 = 150.13 g/mol x 2.28 moles = 342.29 g
ii) Ba(HCO3)2
Molar mass of Ba(HCO3)2 = 259.360 g/mol
Mass in grams in 2.28 moles of Ba(HCO3)2 = 259.360 g/mol x 2.28 moles = 591.34 g
ii) SF6
Molar mass of SF6 = 146.06 g/mol
Mass in grams in 2.28 moles of SF6 = 146.06 g/mol x 2.28 moles = 333.01 g
B) Dinitrogen oxide (or nitrous oxide), N2O, also known as laughing gas, is widely used as an anesthetic in dentistry.
1. How many grams are in 1.30 moles of dinitrogen oxide?
Molar mass of dinitrogen oxide = 44.013 g/mol
Mass in grams in 1.30 moles of dinitrogen oxide = 44.013 g/mol x 1.30 moles = 57.21 g
2. How many moles are in 35.0 g of dinitrogen oxide?
Molar mass of dinitrogen oxide = 44.013 g/mol
Moles in 35.0 g of dinitrogen oxide = 35.0 g/ (44.013 g/mol) = 0.795 moles
