Question

100 g of NaOH was dissolved in 1000 ml of water. Calculate the g/L and mol/L [ Na =40, O =16 and

H =1]

​

Answer 1

Answer:

100g/L and 2.5mol/L

Explanation:

g/L = 100g/1L = 100g/L ( Since 1000mL= 1L) (Ans)

Mass of NaOH = 40g

So, no. of moles in 100 g NaOH = 100/40 = 2.5

So, mol/L = 2.5/1 = 2.5 mol/L (Ans)
