Edexcel IGCSE Physics Problem Solving and Application Topic Practice

This question is about liquid nitrogen.

A teacher uses this method to find the density of liquid nitrogen.
- measure the mass of a container
- pour liquid nitrogen into the container
- measure the total mass of the container and the liquid nitrogen
- read the volume of the liquid nitrogen from the scale on the side of the container

The table shows the teacher's results.

Calculate the mass of liquid nitrogen in the container.
mass $=\ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots . . \mathrm{g}$
