Question

Avogadro law numerical question​

Answer 1

Answer:

Avogadro's law says the volume (V) is directly proportional to the number of molecules of gas (n) at the same temperature. This means the ratio of n to V is equal to a constant value. ... You would expect less gas to take up a smaller volume. In this case, 2 moles of gas only took up 20 L

Answer 2

Answer:

Example Problem

A 6.00 L sample at 25.0 °C and 2.00 atm contains 0.500 mol of gas. If we add 0.250 mol of gas at the same pressure and temperature, what is the final total volume of the gas?

Solution

The formula for Avogadro's law is:

V
