Question

Find the number of moles of sodium chloride solution.​

Answer 1

Answer:

Rounding to one decimal place, the mass of one mole of sodium (Na) is 23.0 grams and that of chlorine (Cl) is 35.5 grams, so one mole of NaCl has a mass of 58.5 grams. You have 12 grams, which equals 12/58.5 = 0.21 moles.

Answer 2

Answer:

nacl is the symbol of sodium chloride

so, atomic mass of sodium=23

atomic mass of chlorine=35.5

so, (23×1)+(35.5×1)

23+35.5

=58.5 u
