Question

Calculate the number of moles of solute in 24.77 ml of 0.1685 M K,Cr, 0,(aq). moles of solute: mol

Answer 1

in a solution, molarity = (number of moles of solute present in the solution) / (total volume of solution in litre)

therefore,

number of moles of solute present in the solution = molarity x total volume of solution in litre
=(molarity x total volume of solution in ml) / 1000
= (0.1685 x 24.77) / 1000

= 0.004174 moles

= (4.174 * 10^-3) moles
