Josh Burns · Answer 1

No. of moles - = given mass / molar mass

1) 9 g of H2O = 9/18 = 1/2 = 0.5 mole

2) 88g of CO2 = 88/44 = 2moles

3) 1.7 g of NH3 = 1.7/17 = 0.1 mole

Emma Valdez · Answer 2

Number of moles = mass/molar mass

1. 9 g of H2O = 9/18=0.5 moles

2.88 gof CO2=88/44=2 moles

3.70 g of NH3=70/17=4.12 moles
