An student thinks it may be possible to identify different rocks $(\mathrm{A}, \mathrm{B}$ and $\mathrm{C})$ by measuring their densities. She uses an electronic balance to measure the mass of each sample and uses the 'displacement method' to determine the volume of each sample. The diagram shows her displacement results for sample $\mathrm{A}$. State the volume shown in each measuring cylinder.

The table shows the student's readings for samples $\mathrm{B}$ and $\mathrm{C}$.

Copy and complete the table by inserting the appropriate column heading and units, and calculating the densities.

A flask with a tap has a volume of $200 {\mathrm{cm}}^3$.

When full of air, the flask has mass of $30.98 \mathrm{g}$.

The flask is connected to a vacuum pump, the air is pumped out and then the tap is closed.

The flask now has a mass of $30.72 \mathrm{g}$.

Calculate the mass of the air in the flask before connecting to the vacuum pump, in $\mathrm{g}$.
