How many grams of glucose (C6H12O6) can prepare 1750 mL of a 2.50 M solution?

787.5 grams of glucose (C₆H₁₂O₆) can prepare 1750 mL of a 2.50 M solution

Explanation:

Molarity (M) is a concentration measure that indicates the number of moles of solute that are dissolved in a given volume.

Molarity is expressed in the following way:

Molarity is expressed in units .

2.50 M  means that in 1 L of solution there are 2.5 moles of glucose. So, you apply a rule of three as follows: if in 1 L there are 2.5 moles of glucose, in 1.75 L (1750 mL, being 1000 mL = 1 L) how many moles of the compound are there?

moles=4.375

Being:

The molar mass of glucose is:

C₆H₁₂O₆= 6* 12 g/mole+ 12* 1 g/mole + 6* 16 g/mole

C₆H₁₂O₆= 180 g/mole

Then you can apply a rule of three as follows, knowing the moles in 1750 mL and the molar mass: if there are 180 g of glucose in 1 mole, how much mass is there in 4.375 moles?

mass= 787.5 g

787.5 grams of glucose (C₆H₁₂O₆) can prepare 1750 mL of a 2.50 M solution
