### How do you calculate density of a gas?

The ideal gas law is given by: PV = gRT/M, where P = pressure, V= volume, T = temperature, g = weight of the gas R = the ideal gas constant. This equation may be rearranged to give the density of the gas : r = g/V = PM/RT.

**How do you calculate the density of a gas?**

Calculating the density of a gas usually involves combining the formula for density (mass divided by volume) and the ideal gas law (PV = nRT). ρ = PM/RT, where M is molar mass.

**How do you find the density of hydrogen at STP?**

Answer and Explanation: We are asked to find the density of hydrogen gas at STP. We will use the equation d=PMRT d = P M R T . At STP, T= 273.15 K and P = 1.0 atm….

## What is the density of liquid hydrogen?

71 kg/m3

In the liquid form At -252.87°C and 1.013 bar, liquid hydrogen has a density of close to 71 kg/m3.

**What is the volume of 1 kg of hydrogen?**

11.2 m3

Specific heat of hydrogen at constant volume is 10046J kg ‘K-.

**How do you find the density of hydrogen at different pressures?**

If pressure is given in psia, you have to multiply the density at 14.5 psia with the actual higher pressure (in psia) and divide by 14.5. Note! For pressure between 20 and 100 bara, the error may be up to 7% by using this approximation (higher error, the higher pressure). Example 1: Density of hydrogen at 5 bara and 24 °C.

**What is the density of hydrogen at 5 Bara?**

Example 1: Density of hydrogen at 5 bara and 24 °C. Calculator gives the density at 24 °C and 1 bara: 0.0815 [kg/m 3] Density at 24°C and 5 bara: 0.0815 [kg/m 3 ]* 5 [bara]/1 [bara] = 0.408 [kg/m3] Example 2: Density of hydrogen at 725 psia and 125 °F.

**How do you calculate the output density of a gas?**

The output density is given as kg/m 3, lb/ft 3, lb/gal (US liq) and sl/ft 3 . Specific weight is given as N/m 3 and lb f / ft 3. For calculation of density at higher pressure (up to 100 bara / 1450 psia), a good approximation is to multiply the density at 1 bara with the actual, higher pressure (in bara).
