Question

$calculate \: \: the \: \: mass \: \: of \: \: the \: \: following \\ \\ 0.5 \: \: mole \: \: of \: \: N_{2} \: \: gas \\ (mass \: \: from \: \: mole \: \: of \: \: molecule)$
​

Answer 1

Answer:

14g

Step-by-step explanation:

No. of moles = $\frac{mass}{molar mass}$

Molar mass of N₂ = (14 + 14) = 28

No. of moles = 0.5 mol

$0.5 = \frac{mass}{28} \\\\mass = 28*0.5\\\\mass=14.0$
