Question 7

Sulfur dioxide and oxygen react in a reactor.

$2SO2+O2→2SO32\text{SO}_2 + \text{O}_2 \rightarrow 2\text{SO}_3$

During one batch, 80 cm³ of sulfur dioxide reacts. After the reaction has finished, 25 cm³ of oxygen remains.

All gas volumes are measured at the same temperature and pressure.

What volume of oxygen was supplied to the reactor?

[1]

$cm325\ \text{cm}^3$

$cm365\ \text{cm}^3$

$cm3105\ \text{cm}^3$

$cm340\ \text{cm}^3$
