On what factors do the values of the gas constant $R$ depend? What is its unit?

Volume of a given mass of gas at $17 \, ^oC$ is measured as $200 \, cm^3$. The volume of the same mass of that gas at same pressure and at temperature of $47 \, ^oC$ will be .............. $cm^{3}$

At $T \ (K)$ for one mole of an ideal gas,the graph of $P$ (on $y$-axis) and $V^{-1}$ (on $x$-axis) gave a straight line with a slope of $32.8 \ L \ atm \ mol^{-1}$. What is the temperature (in $K$)? $\left(R=0.082 \ L \ atm \ K^{-1} \ mol^{-1}\right)$

The gram molecular volume of an ideal gas at $STP$ is $22400 \ cm^{3}$. However,for oxygen gas,the question asks for the volume. Given the options provided,the correct value for $1 \ \text{mole}$ of any ideal gas at $STP$ is $22400 \ cm^{3}$. Please note that the provided solution in the prompt was incorrect. (in $cm^{3}$)

Two closed bulbs of equal volume $V$ containing an ideal gas initially at pressure $P_i$ and temperature $T_1$ are connected through a narrow tube of negligible volume as shown in the figure below. The temperature of one of the bulbs is then raised to $T_2$. The final pressure $P_f$ is:

Explain the relationship between pressure,volume,and density of gases.
