Calculate the number of moles in each of the following 15.0g NH3

0.88mole

Explanation:

The number of mole present in 15g of NH3 can be obtained as follow:

Molar Mass of NH3 = 14 + (3x1) = 14 + 3 = 17g/mol

Mass of NH3 = 15g

Number of mole of NH3 = ?

Number of mole = Mass / Molar Mass

Number of mole of NH3 = 15/17

Number of mole of NH3 = 0.88mole
