Answer:
20uL of protein, 980uL of water
Explanation:
According to the question, a protein extract is about to be prepared using a 1:50 dilution of the extract in a total volume of 1000uL.
1:50 means there will be;
1/50 part of protein and 49/50 part of water.
Hence, in a total volume of 1000uL, one would need:
Protein extract: 1/50 × 1000 = 20
Water: 49/50 × 1000 = 980
Therefore, 20uL of protein and 980uL of water will be needed to make a 1000uL solution containing protein extract and water in the ratio 1:50
