The mass of 1.5 moles of $C O_{2}$ $CO_2$ is 66 grams

Explanation:

Let:
$n$ $n$ be the number of moles
$m$ $m$ be the mass
$M$ $M$ be the molecular weight

$n = 1.5 m o l$ $n = 1.5mol$

By definition:

$n = \frac{m}{M}$ $n = m/M$

$m = n \cdot M$ $m = n*M$

$M (C) = 12 g / m o l$ $M(C) = 12g//mol$
$M (O_{2}) = 2 \cdot 16 g / m o l = 32 g / m o l$ $M(O_2) = 2*16g//mol= 32g//mol$
$M = 12 g / m o l + 32 g / m o l$ $M = 12g//mol + 32g//mol$
$M = 44 g / m o l$ $M = 44g//mol$

$m = 1.5 m o l \cdot 44 g / m o l$ $m = 1.5mol*44g//mol$
$m = 66 g$ $m = 66g$
