# A gas occupies #"0.5650 L"# in a closed container. The initial pressure is #"______"# if the volume increases to #"1.204 L"# at a pressure of #"715.1 bar"#?

##### 1 Answer

The initial pressure, which goes in the blank, was

#### Explanation:

This question involves **Boyle's gas law** , which states that the volume of a given amount of a gas varies inversely with the pressure, as long as temperature is kept constant. This means that when the volume increases, the pressure decreases, and vice-versa. The equation you will need to answer this question is:

In your question, the blank is the initial pressure,

**Known**

**Solution**

Rearrange the equation above to isolate
