In the ideal gas law, the variable n represents O the ideal gas constant
O number of Joules
O the number of moles
O the number of neutrons

C: The number of moles

Explanation:

The ideal gas law is simply the general gas equation for a hypothetical gas and the formula for this ideal gas law is simply;

PV = nRT

Where;

P is pressure

V is volume

n is amount of substance in moles

R is ideal gas constant

T is temperature

Looking at the options, the correct answer is option C.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

the temperature of the gas, in k, not celsius.
