# Solid arsenic reacts with Oxygen gas to synthesize solid arsenic trioxide. How many moles of arsenic trioxide will be produced from 3.4 moles of oxygen gas?

Aug 19, 2017

$2 A {s}_{2} {O}_{3}$ = $2.26$ moles

#### Explanation:

$4 A s$ + $3 {O}_{2}$ -----> $2 A {s}_{2} {O}_{3}$

According to equation
$3$ moles of oxygen gas is required to form arsenic trioxide = $2$ moles
$3.4$ moles of O2 will be required to form Arsenic trioxide = ($2$ x $3.4$) / $3$
= $2.26$ moles
