Question

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

Answer 1

Answer:

The molar amount of gas.

Explanation:

According to the ideal gas law,

PV = nRT

P = pressure of gas

V = volume of gas

n = number of moles of gas

R = ideal gas constant

T= temperature of gas

When pressure, volume and temperature of gas is known the molar amount of gas can be determine by using above formula.

For example:

P = 1.2 atm

R = 0.0821 atm. L.mol⁻¹ .k⁻¹

T =  293 K

V = 2 L

n = ?

Solution:

PV = nRT

1.2 atm × 2L= n × 0.0821 atm. L.mol⁻¹ .k⁻¹ × 293 K

n = 1.2 atm × 2L /   0.0821 atm. L.mol⁻¹ .k⁻¹ × 293 K

n = 0.1 mol
