Calculate the number of moles of sugar in 800 ml of a 2.6 M solution

2.08moles

Explanation:

Given parameters:

Volume of solution = 800mL   = 0.8L

Molarity  = 2.6M

Unknown:

Number of moles of sugar in the solution = ?

Solution:

We need to understand the relationship between number of moles, volume and molarity of a solution.

The molarity of a solution is the number of moles of solute of a substance dissolved in a given solvent.

         Molarity  =

   Number of moles of solute  = molarity x volume of solution

Now input the parameters and solve;

            Number of mole of solute  = 2.6 x 0.8  = 2.08moles

The number of moles of sugar is 2.08moles

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.
