Expert Answer

Step 1

We need to determine the molality of a normal creatinine level in a 30.0 mL blood sample.

Given conditions are:

Creatinine chemical formula= C4H7N3O

Molar mass of Creatinine = 113.12 g/mol

Volume of blood sample = 30.0 mL

Density of blood = 1.025 g/mL

Normal creatinine level in adults’ body = 1.0 mg per deciliter of blood.

Step 2

Firstly, we are calculating mass of blood used in given sample using the density formula:

Step 3

Here we have,

Volume of blood sample = 30.0 mL

Density of b...
