Question

What is the number of moles of solute in 250 mL of a 0.4 M solution?

Answer 1

0,1 mol

Step-by-step explanation:

We know that the formula of concentration is C= moles of solute/ volume

0,4 M= moles of solute/ 250 mL

Convert mL to L 250 mL =0,25 L

0,4 M x 0,25 L= moles of solute

0,1 moles= moles of solute
