10cm 3cute of normal specimen of human blood contains 1.2g of hemoglobin how many grams does 18cm 3cute of the same blood contain?
Please help!
To solve this problem, we can use the concept of ratio and proportion.
First, let's set up a proportion based on the given information:
10 cm^3 of blood contains 1.2 grams of hemoglobin.
Now, we need to find out how many grams of hemoglobin are present in 18 cm^3 of blood. Let's represent this unknown quantity as 'x' grams.
The proportion can be set up as follows:
10 cm^3 / 1.2 g = 18 cm^3 / x g
To solve for 'x', we can cross-multiply and then divide:
10 cm^3 * x g = 18 cm^3 * 1.2 g
10x = 21.6
Divide both sides by 10 to isolate 'x':
x = 21.6 / 10
x = 2.16 grams
Therefore, 18 cm^3 of the same blood would contain 2.16 grams of hemoglobin.
