State the meaning of the term ideal gas.
An ideal gas made of single atoms is inside a cylinder and has a volume of $1.84 \times 10^{-2}\,\text{m}^{3}$ at a pressure of $2.12 \times 10^{7}\,\text{Pa}$. The mass of gas in the cylinder is $3.20\,\text{kg}$. Determine, to three significant figures, the root-mean-square (r.m.s.) speed of the atoms of the gas.
The gas temperature in the cylinder is $22^{\circ}\text{C}$. Determine, to three significant figures, the amount, in mol, of the gas.
Determine, to three significant figures, the mass of a single atom of the gas.
Use your answer in (b)(ii) part 2 to determine the nucleon number $A$ for an atom of the gas.
Determine, to three significant figures, the amount, in mol, of the gas.
Determine, to three significant figures, the mass of a single atom of the gas.
