Question

What volume of each solution contains 0.14 mol of KCl? Express your answer using two significant figures.

Answer 1

$\:$

1 mole of KCl → 22.4l

1 mole of KCl → 74.55g

we have

0.14 mole of KCl → 74.55*0.14=10.347g

74.55g of KCl  → 22.4l

10.347 g of KCl → 22.4/74.55*10.347=3.11litre

volume of each solution contains 0.14 mol of KCl contain 3.11litre.

Answer 2

Answer:

Solution given:

1 mole of KCl$\rightarrow$22.4l

1 mole of KCl$\rightarrow$74.55g

we have

0.14 mole of KCl$\rightarrow$74.55*0.14=10.347g

74.55g of KCl$\rightarrow$22.4l

10.347 g of KCl$\rightarrow$22.4/74.55*10.347=3.11litre

volume of each solution contains 0.14 mol of KCl contain 3.11litre.
