Question

Calculate the number of moles in 44.8 litres of carbon dioxide at STP

Answer 1

Hey friend 

Here is your answer

At STP, one mole of gas has a volume of 22.4 liters.

Given that there are 44.8 liters in this problem, which is twice as much as 22.4, there must be 2.00 moles of Carbon Dioxide CO2 gas.

Answer 2

The number of moles in 44.8 litres of carbon dioxide at STP is 2.

Given,

Volume of carbon dioxide gas = 44.8 litres  

We know that, at STP ; 22.4 litres = 1 mole of gas

Therefore,

$44.8l=(\frac{1}{22.4} )\times 44.8$

        $=2$ moles of gas.

Hence, we can say that at STP the 44.8 L of carbon dioxide gas contains 2 moles of gas. Here STP indicates the standard temperature and pressure conditions which is 22.4 L volume, at 1 atmospheric pressure and the temperature at 273 K.
