Question

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

a) 7.3g HCl in 100ml solution.
b) 2g NaOH in 50ml solution
c) 3g Acetic acid in 100ml solution
d) 4.9g Sulphuric Acid in 200ml solution​

Answer 1

Answer:

Given:

Weight in grams= 7.3g

Volume in liters = 100 mL = 0.1L (1mL= 1/1000L)

Molecular mass of HCl = 1+ 35.4 = 36.4 g/mol

Concentration in g/L = 73g/L

Concentration in mol/L = 2 mol/L

Thus, concentration in g/L is 73g/L and concentration in mol/L is 2mol/L.
