10 cm^3 of normal specimen of human blood contain 1.2g of hemoglobin. How many grams does 40cm^3 of same blood contain?

Thank you.

1.2/10 = x/40

Solve for x.

To find out how many grams 40 cm^3 of the same blood contains, we can use a proportion to solve the problem.

We know that 10 cm^3 of blood contains 1.2 grams of hemoglobin. Let's set up the proportion:

10 cm^3 / 1.2 g = 40 cm^3 / x g

To solve the proportion, we can cross-multiply:

10 cm^3 * x g = 40 cm^3 * 1.2 g

Now, divide both sides of the equation by 10 cm^3:

x g = (40 cm^3 * 1.2 g) / 10 cm^3

Simplifying this expression gives us:

x g = 48 g / 10 cm^3

Divide 48 g by 10 cm^3 to get the value of x:

x g = 4.8 g

Therefore, 40 cm^3 of the same blood contains 4.8 grams of hemoglobin.
