Question
**Problem Statement:**

A typical 10 cm³ sample of human blood contains 1.2 grams of hemoglobin. Calculate the grams of hemoglobin present in 42 cm³ of the same blood specimen.

**Solution:**

To solve this problem, we need to determine how much hemoglobin is contained in a blood sample that is 4.2 times larger than the initial 10 cm³ sample. 

First, note the amount of hemoglobin per cm³:

- 10 cm³ of blood contains 1.2 grams of hemoglobin.
- Therefore, each cm³ contains 1.2 grams / 10 cm³ = 0.12 grams of hemoglobin.

Next, calculate the amount of hemoglobin in 42 cm³ of blood:

- 42 cm³ × 0.12 grams/cm³ = 5.04 grams

**Conclusion:**

A 42 cm³ sample of the blood contains 5.04 grams of hemoglobin.
