did the test already :)

Answer 2

The number of moles of solute present in 4.00 L of an 8.30 M solution​ is 33.2

Step-by-step explanation:

The Molarity (M) or Molar Concentration is the number of moles of solute per liter of solution; in other words it is the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

`Molarity=(number of moles of solute)/(volume)`

Molarity is expressed in units (
`(moles)/(liter)`) or M.

In this case:

• molarity= 8.30 M
• number of moles of solute= ?
• volume= 4.00 L

Replacing:

`8.30 M=(number of moles of solute)/(4 L)`

Solving:

number of moles of solute= 8.30 M* 4 L= 8.30
`(moles)/(liter)` * 4 L

number of moles of solute =33.2

The number of moles of solute present in 4.00 L of an 8.30 M solution​ is 33.2
