Question

What is the concentration of agcl in an aqueous solution that contains 1.2 x 10 -3 gram of agcl in 800. grams of the solution?

Answer 1

Answer:

= 6.7 × 10^-6 M

Explanation:

The number of moles of AgCl

= 0.0012 g/143.32 g/mol

= 8.373 × 10^-6 Moles

Concentration or Molarity = moles × volume

800 grams = 800 cm³ = 0.8 L

= 8.373 × 10^-6 Moles × 0.8 L

= 6.7 × 10^-6 M
