Question

A sample of gaseous water is composed of 2.34 moles. What is the samples volume at STP ?

Answer 1

The sample's volume at STP is 52.416 L.

Step-by-step explanation:

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

Then you can apply the following rule of three: if 1 mole of a gaseous sample occupies 22.4 L, 2.34 moles how much volume does it occupy?

`Volume=(2.34 moles* 22.4 L)/(1 mole)`

Volume= 52.416 L

The sample's volume at STP is 52.416 L.
