Answer:
The answer to your question is 2.1
Explanation:
Data
Molarity = 1 l
mass = 120 g of NaCl
moles = ?
Formula
Process
1.- Calculate the number of moles of NaCl
Molecular weight NaCl = 23 + 35.5 = 58.5 g
2.- Calculate the number of moles using proportions
58.5 g of NaCl --------------- 1 mol
120.0 g of NaCl --------------- x
x = ( 120 x 1) / 58.5
x = 2.1 moles
3.- Calculate Molarity
Substitution
Simplification and result
Molarity = 2.1
