If the pressure, volume, and temperature of a gas are known, which can most likely be found by using the ideal gas law? the molar amount of the gas the partial pressure of the gas the standard temperature and pressure the molar mass

the molar amount of the gas.

Justification:

The ideal gas law states:

pV = nRT,

where p, V and T are pressure, volume and temperature, the variables known as per the statement.

R is the Universal Constant of Gases (whose value is also known).

So, the unknown is n, which is the number of moles (molar amount) of the gas, threfore you can solve for n from the law.
