Question

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

Answer 1

Answer:

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 T
• While 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/V
• We can, thus see that ideal gas law allows you to calculate number of moles unlike the case with Charles's and Boyle's law.

Answer 2

The quantity does not possible in Boyle's or Charles' law is option d. The number of moles

Ideal gas law:

Here

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.

Based on Boyle's law, the volume and pressure of a fixed mass of a gas are inversely proportional at a constant temperature.

Now based on this, we can say that the volume, pressure, and temperature should be considered.
