Question

what is the molar mass of nh3? (h = 1.01 g/mol, n = 14.01 g/mol)

Explanation:

Step1: Calculate the mass of hydrogen in \(NH_3\)

There are 3 hydrogen atoms in \(NH_3\). The mass of one hydrogen atom is \(1.01\ g/mol\). So the mass of hydrogen in \(NH_3\) is \(3\times1.01\ g/mol\).
$$3\times1.01\ g/mol = 3.03\ g/mol$$

Step2: Calculate the molar mass of \(NH_3\)

The molar mass of \(NH_3\) is the sum of the molar mass of nitrogen and the molar mass of hydrogen in it. The molar mass of nitrogen is \(14.01\ g/mol\).
$$Molar\ mass\ of\ NH_3=14.01\ g/mol + 3.03\ g/mol$$
$$Molar\ mass\ of\ NH_3 = 17.04\ g/mol$$

Answer:

\(17.04\ g/mol\)
