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?

Temperature

Explanation:

According to the ideal gas equation, which is a combination of Boyle's law, Charle's law , Gay lussac's law and Avogadro's law.

P = Pressure of the gas

V= Volume of the gas

T= Temperature of the gas

R= Gas constant  

n=  moles of gas

Thus if pressure, volume and the number of moles of a gas are known, temperature is needed to calculate the gas constant.

we need the questions , i may then you.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
