What is the volume of 43.7 g of helium at stp?

Answer : The volume of helium gas is, 244.72 liters

Explanation : Given,

Mass of helium gas = 43.7 g

Molar mass of helium gas = 4 g/mole

As we know that at STP, 1 mole of gas contains 22.4 liter volume of gas.

First we have to calculate the moles of helium gas.

Now we have to calculate the volume of helium gas.

As, 1 mole of helium gas contains 22.4 liter volume of gas

So, 10.925 mole of helium gas contains liter volume of gas

Therefore, the volume of helium gas is, 244.72 liters

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
