# Calculate the volume of carbon dioxide gas lost at 25 degrees and 100kPa?

##
Initial mass (g) = 125.5

Final mass (g) = 124.8

Change in mass (g) = 0.7

Initial mass (g) = 125.5

Final mass (g) = 124.8

Change in mass (g) = 0.7

#### Explanation:

Use the Ideal Gas Law:

For the initial mass of

Remember, the formula for moles,

Here,

So

So now, we can rearrange the gas law:

For the final mass of

Here,

So

Therefore, the total loss must be

So the loss is equal to
