Question

the molar mass of nitrogen gas (n₂) is (round to the nearest tenths place) g/mol

Explanation:

Step1: Find the atomic mass of nitrogen

The atomic mass of nitrogen (\(N\)) is \(14.0\space g/mol\) (from the periodic table).

Step2: Calculate the molar mass of \(N_2\)

Since \(N_2\) has 2 nitrogen atoms, the molar mass \(M = 2\times14.0\space g/mol\).

$$M=28.0\space g/mol$$

Answer:

\(28.0\space g/mol\)
