The density of oxygen gas at $1.0 \, atm$ pressure and $27 \, ^oC$ temperature is ............. $g/L$.

If $P, V,$ and $T$ represent the pressure,volume,and temperature of a gas,respectively,which of the following represents Boyle's Law correctly?

Which of the following statements is false?

At $27\,^oC$ temperature in a $2\, L$ closed vessel,$10\, g$ of $H_2$ and $22\, g$ of $CO_2$ gases are filled. Find the partial pressure of each gas and the total pressure of the mixture. (Use $R = 0.08314\, L \cdot bar \cdot K^{-1} \cdot mol^{-1}$ and formula $pV = nRT$)

What is the numerical value of gas constant $R$ in terms of $L \ atm \ K^{-1} \ mol^{-1}$?

If the absolute temperature of an ideal gas becomes double and the pressure becomes half,the volume of the gas would be:
