## How do you find volume when given temperature and mass and pressure?

You use the gas formula V = nRT/P, where V is the volume, P and T are the pressure and the temperature (T in kelvins), n is the number of moles of gas, and R is the universal gas constant, R = 8.31451 joules/kelvin/mole.

**How do you work out the volume of a prism?**

To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.

**How do you find volume when temperature and pressure are changed?**

First, let’s review the ideal gas law, PV = nRT. In this equation, ‘P’ is the pressure in atmospheres, ‘V’ is the volume in liters, ‘n’ is the number of particles in moles, ‘T’ is the temperature in Kelvin and ‘R’ is the ideal gas constant (0.0821 liter atmospheres per moles Kelvin).

### How do you find volume when given temperature?

V₂ = V₁ / T₁ * T₂ . If you prefer to set the final volume and want to estimate the resulting temperature, then the equation of Charles’ law changes to: T₂ = T₁ / V₁ * V₂ . In advanced mode, you can also define the pressure and see how many moles of atoms or molecules there are in a container.

**What is N in PV NkT?**

The ideal gas law states that PV = NkT, where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the gas, and T is its absolute temperature.

**How do you find temperature when given temperature and volume?**

#### What is R Chem?

Chemistry and physics equations commonly include “R”, which is the symbol for the gas constant, molar gas constant, ideal gas constant, or universal gas constant.

**How do you find the number of moles given volume pressure and temperature?**

Multiply the volume and pressure and divide the product by the temperature and the molar gas constant to calculate moles of the hydrogen gas. In the example, the amount of hydrogen is 202,650 x 0.025 / 293.15 x 8.314472 = 2.078 moles.

**How do you find the volume of a substance with mass?**

If you know the mass and the molar mass ( or identity of the gas so you can calculate the molar mass), then you can calculate moles and use the ideal gas law in the less likely case that the substance is a solid or liquid, you need the mass and the density to find volume.

## How do I calculate the pressure and volume in moles?

Select the n (Amount in moles) in the Select an unknown selector. Enter the pressure P = 500 kPa. Enter the temperature T = 15 °C. Enter the volume V = 5 L. Click or press the Calculate button. The calculator will calculate the quantity in moles that will be used later. Change the Select an unknown selector to the Volume.

**How do you find the volume of a pressure vessel?**

ie. to find a volume you would need to know the start pressure, temperature and volume plus finish pressure and temperature. To be mathematically correct the temperature variable must be ‘absolute’ for the formula to work accurately, Kelvin or Rankin.

**What is the formula for the pressure of a gas?**

The equations describing these laws are special cases of the ideal gas law, PV = nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of the gas, T is its kelvin temperature, and R is the ideal (universal) gas constant.
