What is the amount of sodium hydroxide, NaOH, in 4.6 g? Use the values given for the atomic mass of Na, H, and O.
6
Na = 22.989 770 u
H = 1.007 94u
0 = 15.99944
9
a) 0.19 mol
12
b) 0.12 mol
15
c) 1.8 x 102 mol
d) 0.20 mol

 0.12 Mol

Explanation:  Molecular mass of NaOH is = 39,997 g/mol which is Atomic mass of Na + Atomic Mass of H + Atomic mass of O

4.6g / 39.997g/mol = 0.12 mol

take a better picture and ill do it

a graduated cylinder.
