Calculate the moles of ammonia present in a 4.652 g sample if the molar mass of ammonia is 17.030 g/mol.

0.273mole

Explanation:

Data obtained from the question include:

Mass of ammonia = 4.652g

Molar Mass of ammonia = 17.030g/mol

Number of mole of ammonia = ?

Number of mole = Mass / Molar Mass

Number of mole of ammonia = 4.652/17.030

Number of mole of ammonia = 0.273mole

Therefore, there are 0.273mole of ammonia in 4.652g of ammonia
