Question

For an aqueous solution of glucose (C6H12O6), determine: A) The molarity of 2.00 L of a solution that contains 50.0 g of glucose

Answer 1

Answer:

0.139 ML⁻¹

Explanation:

The Molarity (M) of a solution is the no of moles (amount) of a solute dissolved in a litre of solution.

M = no of moles / 1 litre of solution of solution

The first step is to calculate the no of moles of Glucose contained in 50g of it

No of moles of glucose  = mass/ molar mass of glucose

                                        = 50g / (180.156)g/mol

                                        = 0.27753≅0.278 moles of glucose

Therefore, the molarity of glucose in 2L of solution

                                         = 0.278 moles / 2 lites

                                         = 0.139M/Litre of glucose

                                         = 0.139 ML⁻¹ of glucose
