Answer to Question #117867 in General Chemistry for Jessie

Question

12.5 g barium chloride dissolves in 250 ml of solution. Calculate the mass percent concentration.

Answer 1

Solution.

$m(BaCl_2)=12.5g;$

$V=250mL=0.25L;$

$w(BaCl_2)=\dfrac{m(BaCl_2)}{V};$

$w(BaCl_2)=\dfrac{12.5g}{250mL}=0.05g/mL;$

Answer: $w(BaCl_2)=0.05g/mL.$
