A patient’s urine sample has a density of 1.02 g/ml. If 1250 mL of urine was excreted by the patient in one day, what mass of urine was eliminated?


A) 1.28 kg

B) 1225 g

C) 1275 g

D) 128 g

Respuesta :

Hey there!

Density of urine = 1.02 g/mL

Volume of urine = 1250 mL  

We know density = mass / volume

Thus mass of urine excreted in one day :

mass of urine = density x volume

mass of urine = 1.02 g/mL x 1250mL

mass of urine = 1275 g

Thus the option C is correct

Answer:

The correct answer is option C.

Explanation:

To calculate mass of a substance, we use the equation:

[tex]\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}[/tex]

We are given:

Density of patient’s urine = d = 1.02 g/mL

Mass of liquid = m =?

Volume of patient’s urine =V= 1250 mL

Putting values in above equation, we get:

[tex]d=1.02 g/mL=\frac{m}{1250 mL}[/tex]

[tex]m=1.02 g/mL\times 1250 mL=1,275 g[/tex]

1,275  grams of urine was eliminated.
