Question
A solution is prepared by dissolvint 24.5 g of sodium hydroxide in distilled water to give 1L solution. The molarityof NaOH in the solution is
(Give that molar mass of NaOH = 40.0 g mol-1)
(Give that molar mass of NaOH = 40.0 g mol-1)
Options
A.0.2450 M
B.0.6125 M
C.0.9800 M
D.1.6326 M
Solution
Given WNaOH = 24.5g
No. of moles of NaOH =
moles
= 0.6125 moles
∴ Molarity of solution
=
= 0.6125 M
No. of moles of NaOH =
moles = 0.6125 moles
∴ Molarity of solution
=
= 0.6125 MCreate a free account to view solution
