WebOct 5, 2024 · A gas does not have a definite mass. A gas does not have a definite volume. A gas does not always weigh the same or take up the same amount of space. However, like … WebJul 1, 2024 · Avogadro's Law shows that volume or pressure is directly proportional to the number of moles of gas. Putting these together leaves us with the following equation: P1 × V1 T1 × n1 = P2 × V2 T2 × n2. As with the other gas laws, we can also say that (P × V) (T × n) is equal to a constant. The constant can be evaluated provided that the gas ... customer service mercury insurance
