Q. 6 B4.5( 27 Votes )

Write down the concentration of each of the following solutions in g/L and mol/L.

2g NaOH in 50ml solution

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.
