What is the molarity of a solution which has a volume of 3 litres and contains 5.1 moles of Br2?

The molarity of the solution is 1.7 .

Explanation:

Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.

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

Molarity is expressed in units .

In this case, you know:

Replacing:

Solving:

Molarity= 1.7

The molarity of the solution is 1.7 .

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

there are two significant figures.
