If the pressure, volume, and the number of moles of a gas are known, which is needed to calculate the universal gas constant from the ideal gas law? the temperature of the gas the molar volume of the gas the molar mass of the gas the partial pressure of the gas

The ideal gas law describes the relationship between the pressure, volume, temperature, and number of moles of a gas in this way:
PV = nRT , where R is the universal gas constant. 

Therefore, we are missing the temperature of the gas if we want to calculate the universal gas constant. 

Hydrogen is the most abundant element on the periodic table..hope it .
