Answer:
= 9.6125M
Explanation:
data:
volume = 800ml
800/ 1000 = 0.8dm^3
molar mass of NaCl = 23 + 35.5
= 58.5g
mass of NaCl = 450 g
moles= ?
molarity = ?
solution:
no. of moles = [tex]\frac{given mass}{molar mass}[/tex]
= 450 / 58.5
= 7.69 moles
now, molarity = [tex]\frac{moles}{volume in dm^3}[/tex]
= 7.69 / 0.8
molarity= 9.6125 M
