If a physician orders 600 mL of a fluid that weighs 1.02 g/mL, what is the weight of the fluid in grams?

To find the weight of the fluid in grams, you need to use the relationship between volume, density, and mass. The formula to calculate mass (weight) is:

[ \text{Mass} = \text{Volume} \times \text{Density} ]

In this case, the physician has ordered 600 mL of a fluid with a density of 1.02 g/mL. Plugging the values into the formula gives:

[ \text{Mass} = 600 , \text{mL} \times 1.02 , \text{g/mL} ]

Calculating this:

[ \text{Mass} = 600 \times 1.02 = 612 , \text{g} ]

Thus, the weight of the fluid in grams is 612 g, which corresponds with the choice identified. This calculation shows a direct application of the fundamental concepts of volume and density in determining mass, which is vital in medical settings for accurate medication dosing and fluid management.
