2.50% (w/w) means that 2.50 g of glycine is present in 100 g of solution. 
To find out how much glycine is present in a sample of 250 g of solution, we can use the following proportion: 
2.50 g glycine / 100 g solution = x g glycine / 250 g solution 
Solving for x, we get: 
x = (2.50 g glycine / 100 g solution) * 250 g solution 
x = 6.25 g glycine 
Therefore, the answer is C) 6.25 g.
