# One mole of chlorine gas is equal to how many grams?

Jun 14, 2016

$m a s s = 71 g$

#### Explanation:

apply the $m o l s = \frac{m a s s}{a r}$ where ar is the atomic relative mass.
So it tells us that is chlorine gas and the Ar will be 71 instead of 35.5
as it is $C {l}_{2}$
now
$m o l = 1$
$A r = 71$
mass=?
$1 \cdot 71 = m a s s$
$m a s s = 71 g$
