Question

You have 500 mL of 2 M NaCl solution. How many grams of NaCl did you add?

Answer 1

Answer:

15 g

Explanation:

Answer 2

Answer: 58.44

concentration of NaCl = 2M

Volume = 500ml = 0.5L

No of mole of NaCl = conc. *volume

No of mole of NaCl = 0.5*2 = 1mol

Molar mass of NaCl = 58.44g/mol

Mass of NaCl = Molar mass * no of mole

Mass of NaCl = 1*58.44 = 58.44g

58.44g of NaCl was added
