<h3><u>Answer and explanation;</u></h3>
Ideal gas law is the mathematical relationship among pressure, volume, temperature, and the number of moles of a gas.
The ideal gas law is given by;
PV=nRT, where
P is the Pressure
V is the volume of the gas.
n is the number of moles
R is the gas constant and
T is the temperature
This question refers to significant figures. The reason we follow significant figure rules when performing calculations in science is that a calculated answer (which is an extrapolation of a manipulation of measurements) can only be as precise as the least precise measurement recorded. This means if you record measurements to a certain precision, the calculated answer at the most can only match the recorded level of precision as to balance the level of confidence in accuracy before and after calculations.
