pls answer this question

​

Answer 1

Answer:

option b is correct

Explanation:

calorific value: energy released when 1kg of fuel undergoes complete combustion.

In the question 1mol of butane produce 980kj of energy.

molar mass of butane= 4×12+10×1

= 48+10 => 58 g

So,

58g of butane gives 980kj of energy

1000g(1kg) of butane will give

$\frac{980}{58} \times 1000$

=16896 ki/mol

hope it helps
