Question

compound with empirical formula C3H7,the weight in its half mole is 0.043×103.what will be its molecular formula.​

Answer 1

Answer:

C6H14

Explanation:

Empirical formula is given C3H7

Empirical formula weight is equal to 43

1/2 mole weighs 43 g

1 mole weighs 86 g

we know that mass of 1 mole of a compound is its molecular weight.

so molecular weight of compound is 86

we know;

n= molecular weight/ empirical formula weight

so n = 86/43

n = 2

so molecular formula is 2(C3H7)

which is C6H14.
