Question

Seawater is typically 0.60 M NaCl. How many grams of salt are in 200.0 mL of seawater?

Answer 1

Answer:

M = weight of NaCl * 1000 / molecular weight of NaCl * vol(ml)

0.6 = weight of NaCl * 1000 / 58.5 * 200

weight of Nacl = 0.6 * 58.5 * 200 / 1000

                         =  7.02 gm

Therefore, 7.02 gm of salt are in 200.0 ml of sea water,

Hope it helps you.
