What is the mass

of 2.34 mols of

NH3?

Mass = 39.78 g

Explanation:

Given dа ta:

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
