Moles in the desired diluted evolution = 0.245 mol calculate the moles of hydroc

Question

Moles in the desired diluted evolution = 0.245 mol calculate the moles of hydrochloric acid m the desired diluted solution from the equation Moles of substance = Volume of solution times Concentration of solution Moles (mol) 0.2500 L times 0.240 M Moles = 0 06250 mol Remember to first convert any volume in mL to L by dividing by 1000 Determine the moles of hydrochloric acid that need to be taken from the concentrated solution (To avoid introducing rounding errors on intermediate calculations, enter your answer to four significant figures) Moles from the concentrated solution = mol

Explanation / Answer

Number of moles ,n=concentration x volume in L

n= 0.250 mol x 250 ml x 10^-3 L/ml

= 0.0625 mol
