Question

find the formula mass of NaCl and NaOH
(Na is 23 Cl is 35.5 O is 16 H is 1) plz...fast tomorrow is exam​

Answer 1

Answer:

NaCl = 58.5 g NaOH = 40g

Explanation:

Formula mass = sum of masses of all elements in the compound

Formula Mass of NaCl = 23(Na) + 35.5(Cl)

                                     = 58.5 g

Formula Mass of NaOH = 23(Na)+ 16(O) + 1(H)

                                        =40g
