Atomic mass of nitrogen is 14

molar mass of is 14×2 = 28×0.5=14g

molar mass of is 14×2 = 28×0.5=14g

**mass of 1 mole of nitrogen gas (N₂ ) = 14 * 2 = 28 gram**

**therefore mass in 0.5 moles is ,**

**= 28 * 0.5**

**= 14 .0**

**therefore mass of 0.5 moles of N₂ = 14 grams .**

**i hope it helps.........................^_^**
