Question

what is volume of carbon dioxide ,CO2 occupying by 1 ) 5 moles and 2) 0.5 mole of CO2, gas measured at STP
​

Answer 1

Answer:

at STP 1 mole= 22.4 lt

so,(1) 5 mole =112 lt

(2) 1/2 mole =11.2 lt

Answer 2

Answer :

(1) The volume of carbon dioxide occupying by 5 moles of carbon dioxide are, 112 L

(2) The volume of carbon dioxide occupying by 0.5 moles of carbon dioxide are, 11.2 L

Explanation:

(1) We have to calculate the volume of carbon dioxide for 5 moles of carbon dioxide.

As we know that at STP, 1 mole of substance contains 22.4 L volume of substance.

As, 1 mole of carbon dioxide contains 22.4 L volume of carbon dioxide

So, 5 mole of carbon dioxide contains $5\times 22.4=112L$ volume of carbon dioxide

(2) Now we have to calculate the volume of carbon dioxide for 0.5 moles of carbon dioxide.

As we know that at STP, 1 mole of substance contains 22.4 L volume of substance.

As, 1 mole of carbon dioxide contains 22.4 L volume of carbon dioxide

So, 0.5 mole of carbon dioxide contains $5\times 22.4=11.2L$ volume of carbon dioxide
