Question

Calculate the quantity of glucose needed to prepare 750ml of 25% glucose solution?

Answer 1

Step-by-step explanation:

Given Calculate the quantity of glucose needed to prepare 750 ml of 25% glucose solution?

• Given mass of solution is 750 ml
• Mass of glucose solution by percentage = 25%
• So we have concentration = mass of solute / mass of solution x 100
•                              25 = mass of glucose / 750 x 100
•                        Or mass of glucose = 25 x 750 / 100
•                                                          = 25 x 75 / 10
•                                                         = 1875 / 10
•                                                       = 187.5 ml
• Therefore quantity of glucose needed will be 187.5 ml
