Question

2g NAOH in 50ml solution
​

Answer 1

Answer :

Given:

Weight in grams= 2g

Volume in liters = 50 mL = 0.05L (1mL= 1/1000L)

Molecular mass of NaOH = 23+16+1 = 40 g/mol

Concentration in g/L = 40g/L

Concentration in mol/L = 1 mol/L

Thus, concentration in g/L is 40g/L and concentration in mol/L is 1mol/L.
