Answer to Question #303874 in General Chemistry for gelo

Question

95 ppm concentration is found in a solution with a total volume of 1500 mL, calculate the unknown volume of solute.

Answer 1

1500ml = 1500g

ppm = mass of solute/mass of sample× 1000000

95 = mass of solute/1500g ×1000000

mass of solute= (95ppm× 1500g) ÷ 1000000

= 0.1425g

volume of solute therefore;

= 0.1425ml
