Answer:
The answer to your question is 65.8 grams of NaCl
Explanation:
Data
[NaCl] = 2.25 M
volume = 500 ml = 0.5 l
mass of NaCl = ?
Process
1.- Calculate the moles of NaCl
Molarity = moles / volume
-Solve for moles
moles = Molarity x volume
-Substitution
moles = 2.25 x 0.5
-Result
moles = 1.125
2.- calculate the molar mass of NaCl
NaCl = 23 + 35.5 = 58.5 g
3.- Calculate the mass of NaCl
58.5 g of NaCl -------------------- 1 mol
x -------------------- 1.125 moles
x = (1.125 x 58.5) / 1
x = 65.8 grams
