2.25g

Rationale: There are 2.25g of NaCl in 500 mL of  NS (0.45). To calculate this answer, convert  (0.45) to a decimal (0.0045). Then, solve it by using the following equation: FVX (decimal) = Amount of AI (g) or 500 mL x 0.0045 = 2.25g

0.5

Rationale: The specific gravity would be 0.5 . Use this formula: Specific Gravity (SG) = weight / volume. Therefore, SG = 50 / 85.
