Answers
Assuming the concentration of stock solution is 50% sodium phosphate buffer solution, the volume of stock solution required is 6 mL and the volume of water required is 6 mL.
What volume of a stock Sodium phosphate buffer and water is needed to 12 mL of 25% sodium phosphate buffer of pH 4?The process of preparing solutions from stock solutions of higher concentration is known as dilution.
Dilution is done with the aid of the dilution formula given below:
C1V1 = C2V2where
C1 is the concentration of stock solutionV1 is the volume of stock solution required to prepare a diluted solution C2 is the concentration of the diluted solution preparedV2 is the final volume of the diluted solutionFrom the data provided:
C1 is not given
V1 is unknown
C2 = 25%
V2 = 12 mL
Assuming C1 is 50% solutionVolume of stock, V1, required is calculated as follows:
V1 = C2V2/C1
V1 = 25 × 12 /50
V1 = 6 mL
Therefore, the volume of stock solution required is 6 mL and the volume of water required is 6 mL.

○ Coefficients in chemical formulas
Answers
The law of multiple proportion account for subscripts in chemical formulas (option A).
What is law of multiple proportion?The law of multiple proportion states that when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
For example, nitrogen dioxide and nitrogen tetroxide have nitrogen to oxygen ratios of 1:2 and 1:4.
This suggests that the law of multiple proportion addresses the subscripts in chemical formulas.
