Question

12g glucose is dissolved in 90 g water. Calculate molarity of water. ​

Answer 1

Explanation:

Molarity = mass of solute/molar mass of solute × volume of solution (in litres)

:: molarity = 12/180×90

= 0.74m

Answer 2

Answer:

49.01M

Explanation:

1) first calculate no. of moles of glucose and water.

2) Then add the given of both to get solution.

3) To convert solution in Litre divide by 1000.

4) Apply the formula you'll get the answer
