Question

The molecular mass of ammonia (NH₃) is 17 g/mol. How many grams of ammonia are in 6 moles of ammonia?

Answer 1

The mass (grams per mole) of NH3 is given. Multiply it by the number of moles.

Answer 2

To calculate the grams of ammonia in 6 moles given the molecular mass of 17 g/mol, multiply the number of moles (6) by the molecular mass, resulting in 102 grams of ammonia.

Step-by-step explanation:

The question asks how many grams of ammonia are in 6 moles of ammonia, given that the molecular mass of ammonia (NH₃) is 17 g/mol. To find the mass of ammonia, we can use the formula:

Mass = number of moles × molecular mass

By plugging in the given values:

Mass = 6 moles × 17 g/mol = 102 grams

This calculation indicates that there are 102 grams of ammonia in 6 moles of ammonia. Conservation of mass also applies here, as the mass of reactants will be equal to the mass of the products in a chemical reaction.
