Answer to Question #195189 in General Chemistry for Tom C

Question

Calculate the molarity of a solution when 600 grams of NaC2H3O2 are added to 2 L of solution

Answer 1

NaC₂H₃O₂ have molar mass =

23 + 2×12 + 3 × 1 + 2×16

= 23 + 24 + 3 + 32

= 82 g / mol .

moles of NaC₂H₃O₂

= 600 / 82

= 7.32 mol.

Molarity = moles / Volume .

= 7.32 / 2

= 3.66
