Question

Calculate the moles of ammonia present in a 5.590 g sample if the molar mass of ammonia is 17.030 g/mol

Answer 1

Number of moles = 0.328 moles.

Step-by-step explanation:

Given the following data;

Mass = 5.590 g

Molar mass = 17.030 g/mol

To find the number of moles;

`Number \; of \; moles = \frac {mass}{molar mass}`

Substituting into the equation, we have

`Number \; of \; moles = \frac {5.590}{17.030}`

Number of moles = 0.328 moles.
