10 cm^3 of a normal specimen of human blood contains 1.2 g of hemoglobin. How many grams does 32 cm^3 of the same blood contain?
To find out how many grams are there in 32 cm^3 of the same blood, we can use a proportion to solve the problem.
The given information is that 10 cm^3 of blood contains 1.2 g of hemoglobin. Let's represent this as a ratio:
10 cm^3 of blood / 1.2 g of hemoglobin
Now, we can set up a proportion to find out how many grams are in 32 cm^3 of the same blood:
10 cm^3 / 1.2 g = 32 cm^3 / x g
To solve this proportion, we can use cross-multiplication:
10 cm^3 * x g = 1.2 g * 32 cm^3
10x = 38.4
Finally, divide both sides of the equation by 10 to solve for x:
x = 38.4 / 10
x = 3.84
Therefore, 32 cm^3 of the same blood contains 3.84 grams.
