Question

14.5 g of gas C4H10 in a container calculate Mr of the gas

Answer 1

[This answer is helpful If you're being asked to calculate the number of moles of  C₄H₁₀]

Answer:

0.25 moles

Explanation:

GIVEN :-

• given mass of the gas in the container = 14. 5 g
• Type of the gas = Butane C₄H₁₀

TO FIND :-

Number of moles of the gas

SOLUTION :-

• $number \: of \: moles \: of \:a\: gas\:\:=\:\: \frac{given\: mass\: of \:the\:gas}{molecular\:mass\:of\:the\:gas}$

   => Calculating the gram molecular mass of C₄H₁₀

= (12 × 4) + (1 × 10)

= 48 + 10

= 58 g

   => Calculating number of moles

=  $\frac{14.5}{58}$

= $\frac{1}{4}$

= $0.25$

ANSWER :-

The container contains 0.25 moles of C₄H₁₀.
