water in it, to the nearest integer, is _______.
Enter your answer
Show full solutionCorrect answer: 47.37
Correct answer
47.37
Step-by-step explanation
Mole fraction of glucose in aqueous solution
= 0.1
Let total mole is 1 mol then mole of glucose will be 0.1 and mole of water will be 0.9.
So mass % of water = 100
= 47.37 47
Let total mole is 1 mol then mole of glucose will be 0.1 and mole of water will be 0.9.
So mass % of water = 100
= 47.37 47
