40 g glucose
Explanation:
I have to assume that you are asking about a 2% m/v solution ( Note that specifying 2% in isolation has no meaning )
2% m/v glucose solution is : 2 g glucose in 100 mL solution
Which is ( multiply by 10): 2% m/v = 20 g glucose in 1000 mL ( = 1.0 L) solution
And so 2%m/v = 40 g glucose in 2000 mL or 2.0 L solution
Answer: 40 g glucose.
