With an increase in temperature,which of the following concentration terms changes?

Which unit of concentration value does not change with change in temperature?

What is molarity?

In a solution of a solute in benzene with a molality of $x \ m$,the mole fraction of the solute is $0.2$. The value of $x$ is ...... .

$10.30 \; mg$ of $O_2$ is dissolved in $1 \; L$ of seawater with a density of $1.03 \; g/mL$. The concentration of $O_2$ in $ppm$ is:

Concentration terms such as mass percentage,$ppm$,mole fraction,and molality are independent of temperature,whereas molarity is a function of temperature. Explain.
