Answer 2

There are 4.48 moles of NH3 in 76.5 grams.

The number of moles of a substance can be calculated using its mass and the molar mass of the substance. The molar mass of NH3 is 17 grams per mole. To convert the mass of NH3 in grams to the number of moles, we divide the mass by the molar mass.

So, the number of moles of NH3 in 76.5 grams can be calculated as:

76.5 g / 17 g/mol = 4.48 moles

It's important to note that the molar mass is a constant for a given substance and can be used to convert between mass, moles, and the number of atoms or molecules. This conversion is crucial in chemical calculations and reactions.
