Question

Calculate the molar concentration of a solution containing 469 grams of C6H12O6 in 82 milliliters of water. The molar mass of C6H12O6 is 180.156 g/mol.

Answer 1

The molar concentration of a solution containing 469 grams of C6H12O6 in 82 milliliters of water is 31.7M.

HOW TO CALCULATE MOLAR CONCENTRATION:

• The molar concentration of a solution can be calculated by dividing the number of moles by its volume.

• According to this question, there are 469 grams of C6H12O6 in 82 milliliters of water.

The number of moles = 469g ÷ 180.156g/mol = 2.6mol

Volume of water in litres = 82/1000 = 0.082L

Concentration of solution = 2.6mol ÷ 0.082L = 31.71M

Therefore, the molar concentration of a solution containing 469 grams of C6H12O6 in 82 milliliters of water is 31.7M.
