Question

Write down the concentration of 3g ch3cooh in 100ml solution in g/L and mol/L

Answer 1

Explanation:

Given:

Weight in g= 3g

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

Molecular mass of CH3COOH = 12+3×1+12+16+16+1

= 60 g/mol

Concentration in g/L = 30g/L

Concentration in mol/L = 0.5 mol/L

Thus, concentration in g/L is 30g/L and concentration in mol/L is 0.5mol/L.

Answer 2

concentration is 0.5g
