117 0g of sodium chloride was dissolved in the ... - JAMB Chemistry 2008 Question
117.0g of sodium chloride was dissolved in the solubility in 1.0dm3 of distilled water at 25oC. Determine the solubility in mol dm-3 of sodium chloride at that temperature
[Na = 23, Cl = 35.5]
[Na = 23, Cl = 35.5]
A
1.0
B
2.0
C
3.0
D
4.0
correct option: b
Relative molecular mass of NaCl = 23 + 35.5 = 55.5 g/mol
No. of mole of NaCl = 117/55.5 = 2.1 mol
No. of mole of NaCl = 117/55.5 = 2.1 mol
