How many grams of carbon are in 36.6 grams in glucose
Lana71 [14]

Answer:

14.64 grams of carbon

Explanation:

The Molecular formula of Glucose is C₆H₁₂O₆.

From the molecular formula, the Molar mass of Glucose is,

Mass of Carbon in Glucose = 6*12 = 72.

Mass of Hydrogen in Glucose = 12*1 = 12.

Mass of Oxygen in Glucose = 6*16 = 96.

Molar mass of Glucose = 72+12+96 = 180 grams.

180 grams of Glucose contains 72 grams of Carbon.

How many grams of Carbon are there in 36.6 grams of Glucose.

180 --> 72

36.6 --> ?

Let it be 'x' grams

Then, by Criss Cross, (x)(180) = (36.6)(72) => x = 14.64 grams.

Therefore 14.64 grams of carbon are there in 36.6 grams in glucose.
