3. The ideal gas law allows you to calculate which quantity that is not possible in Boyle's or Charles' law? a. volume b. pressure c. temperature d. number of moles

d. The number of moles

Explanation;

According to the ideal gas;

P = nRT

where, P is the pressure, n is the number of moles, R is the ideal gas constant and T is the absolute temperature.

Charles's law and Boyle's law revolve around, volume, temperature and pressure.According to Charles's law volume and temperature of a fixed mass of a gas are directly proportional at constant pressure.That is; V α TWhile based on Boyle's law, volume and pressure of a fixed mass of a gas are inversely proportional at constant temperature.That is, Pα 1/VWe can, thus see that ideal gas law allows you to calculate number of moles unlike the case with Charles's and Boyle's law.

D. most models represent a real world object in a simpler way
