192 grams of (NH 4 ) 2 CO 3 (N Molar Mass : 96g ) are dissolved to make 2150 mL of solution , what is the concentration of this
svlad2 [7]

The concentration of a solution of 192 grams dissolved to make 2150 mL of solution is 0.93M. Details about concentration can be found below.

<h3>How to calculate concentration?</h3>

The concentration of a solution can be calculated by dividing the number of moles of the substance by its volume.

no of moles of NH42CO3 = 192g ÷ 96g/mol = 2 mol

Concentration of solution = 2 moles ÷ 2.15L

Concentration of solution = 0.93M

Therefore, the concentration of a solution of 192 grams dissolved to make 2150 mL of solution is 0.93M.
