Question

Calculation of molecule mass of Naoh % of Na in Naoh

Answer 1

answer

mass of na = 22

mass of o = 16

mass of h = 1

total mass = 22+16+1 = 39

Answer 2

Explanation:

mass of Na=23

mass of oxygen=16

mass of hydrogen=1

molecular mass of NaOH=23+16+1=40 a.m.u

percentage of Na in NaOH=23/40×100%

115/2%
