Question

How many liters of a 8.0 % (m/v) glucose solution would you need to obtain 65 g of glucose? Express your answer using two significant figures.

Answer 1

0.81 L

Step-by-step explanation:

Answer 2

Answer: The volume of solution containing the given amount of glucose is 0.81 L

Step-by-step explanation:

We are given:

8.0 % (m/v) glucose solution

This means that 8 grams of glucose is present in 100 mL of solution

To calculate the volume of solution containing 65 g of glucose, we use unitary method:

8 grams of glucose is present in 100 mL of solution.

So, 65 grams of glucose will be present in
`(100mL)/(8g)* 65g=812.5mL` of solution

Converting this into liters, we use the conversion factor:

1 L = 1000 mL

So,
`812.5mL* ((1L)/(1000mL))=0.81L`

Hence, the volume of solution containing the given amount of glucose is 0.81 L
