Question

What is the mass
of 2.34 mols of
NH3?

Answer 1

Mass = 39.78 g

Step-by-step explanation:

Given data:

Mass of ammonia = ?

Number of moles of ammonia = 2.34 mol

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of ammonia = 17 g/mol

Now we will put the values in formula:

Mass = number of moles × molar mass

Mass = 2.34 mol × 17 g/mol

Mass = 39.78 g
