The final volume of helium gas will be

#### Explanation:

This is an example of Boyle's law, which states that the volume of a given amount of gas, held at a constant temperature, will vary inversely with its pressure. This means that when the pressure is increased, the volume will decrease and vice versa

The equation to use is

**Known**

**Unknown**

**Solution**

Rearrange the equation to isolate

The final volume of helium gas will be
