Question

Calculate the mass of the following is 0.5 mole ofN2 GAs

Answer 1

Answer:7 g

Explanation:

Answer 2

given:

$atomic \: mass \: of \: N \: = 14u$

solutions:

$N2 = 2 \times 14 = 28u$

$now , \: 1 \: mole \: of \: N2 \: atom = 28g$

$so,o.5 \: moles \: of \: N2 = 28 \times 0.5$

$thus, \: the \: mass \: of \: N2 \: atom = \red {14}$
