Answer:
The answer to your question is 2.3 g
Step-by-step explanation:
Data
Molecule = NaOH
grams of Na in 4 g of NaOH
Process
1.- Calculate the molecular mass of NaOH
molecular mass = (1 x 23) + (1 x 16) + (1 x 1)
= 23 + 16 + 1
= 40 g
2.- Calculate the atomic mass of sodium
atomic mass = 23 g
3.- Use proportions to solve this problem
40 g of NaOH ---------------- 4 g of NaOH
23 g of Na ---------------- x
x = (4 x 23) / 40
x = 2.3 g
