Question

How many moles of solute are contained in a 500.0 milliliter solution that has a concentration of 0.35 M? 180 moles 0.18 moles 0.70 moles 1.4 moles 0.35 moles

Answer 1

the answer to this question is .18 moles

could you add me as best answer?!

Answer 2

Answer : The number of moles of solute are, 0.175 mole

Explanation : Given,

Molarity of solution = 0.35 M = 0.35 mole/L

Volume of solution =
`500ml=0.5L`

conversion : (1 L = 1000 ml)

Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :

`Molarity=\frac{\text{Moles of solute}}{\text{volume of solution in liters}}`

Now put all the given values in this formula, we get the number of moles of solute.

`0.35mole/L=\frac{\text{Moles of solute}}{0.5L}`

`\text{Moles of solute}=0.175mole`

Therefore, the number of moles of solute are, 0.175 mole
