## How do you calculate the change in volume of a gas?

V = nRT/p = 40 * 8.3144598 * 250 / 101300 = 0.82 m³ .

Ideal gas law equation

1. p is the pressure of the gas, measured in Pa;
2. V is the volume of the gas, measured in m³;
3. n is the amount of substance, measured in moles;
4. R is the ideal gas constant; and.
5. T is the temperature of the gas, measured in Kelvins.

## How do you calculate N in pV nRT?

The equation can be rearranged to work out each of the different terms. For example, to calculate the number of moles, n: pV = nRT is rearranged to n = RT/pV.

## How do you find delta N in chemistry?

Δn = (Total moles of gas on the products side) – (Total moles of gas on the reactants side). Hence ( Delta = (d + c) – (a + b)nonumber ] [The lower case numbers are the exponents]

## How do you calculate volume change?

The change in volume ΔV is very nearly ΔV = 3αVΔT. This equation is usually written as ΔV = βVΔT, where β is the coefficient of volume expansion and β ≈ 3α.
