Final answer:
A 300mL bottle of magnesium citrate is approximately equivalent to 10.144 fluid ounces when using the conversion factor where 1 fluid ounce is approximately 29.5735 mL.
Step-by-step explanation:
The patient is prescribed to drink a 300mL bottle of magnesium citrate and wants to know how many ounces are in the bottle. To convert from milliliters (mL) to fluid ounces, we use the conversion factor that 1 fluid ounce is approximately equal to 29.5735 mL.
To find out how many ounces are in 300 mL, we divide 300 by 29.5735:
300 mL ÷ 29.5735 mL/fl oz ≈ 10.144 fl oz.
Therefore, the 300mL bottle of magnesium citrate is approximately equivalent to 10.144 fluid ounces.
To choose the best unit of measure for liquids like the magnesium citrate or milk in a baby bottle, fluid ounces are typically used in the United States, while milliliters may be used in other countries.
