Calculate the millimoles of solute in 2.25 L of a 0.00645 M NaCN solution. millimoles: mmol NaCN Calculate the millimoles of solute in 275 mL of a 8.89 ppm CaCO 3 solution. millimoles: mmol CaCO 3

 The millimoles of solute in 2.25 L of a 0.00645 M NaCN solution is 14.5 millimoles. The millimoles of solute in 275 mL of a 8.89 ppm solution is 0.0244 millimol.

Explanation:

Molarity is defined as the number of moles of solute dissolved per liter of the solution.

where,

n= moles of solute

= volume of solution in L

1) For 0.00645 M NaCN

2) For 8.89 ppm
