Calculate the number of moles for each of the following:

1. 9.00 g of H\(_2\)O
2. 88.0 g of CO\(_2\)
3. 1.70 g of NH\(_3\)

Asked by Teressa523

Answer (3)

no. of moles -= given mass/ molar mass

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

88g of CO2 = 88/44 = 2moles

1.7 g of NH3 = 1.7/17 = 0.1 mole

number of moles= mass/molar mass

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

The number of moles for each substance are approximately: 0.50 moles of H₂O, 2.00 moles of CO₂, and 0.100 moles of NH₃. These values are calculated using the molar mass of each compound divided into their respective mass. Understanding moles is essential in chemistry for measuring amounts of substances.
