100.0 mL of 3.8M NaCN, the minimum lethal concentration of sodium cyanide in blood serum

The given question is incomplete. The complete question is:

Calculate the number of moles and the mass of the solute in each of the following solution: 100.0 mL of 3.8 × 10−5 M NaCN, the minimum lethal concentration of sodium cyanide in blood serum

The number of moles and the mass of the solute are and respectively

Explanation:

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

where,

n = moles of solute

= volume of solution in ml

n = moles of =

Thus the number of moles and the mass of the solute are and respectively
