Question

2. Glucose, C6H12O6, along with O2 is a product that is produced from photosynthesis of plants. How many grams of carbon are in 16.55 g of glucose

Answer 1

6.62 g of carbon.

Step-by-step explanation:

We'll begin by calculating the molar mass of C6H12O6. This is illustrated below:

Molar mass of C6H12O6 = (12×6) + (12×1) + (16×6)

= 72 + 12 + 96

= 180 g/mol

Next, we shall determine the mass of carbon (C) in 1 mole (i.e 180 g) of C6H12O6. This is illustrated:

Mass of C in C6H12O6 = 6C = 12×6

Mass of C in C6H12O6 = 72 g

Thus, 180 g of glucose contains 72 g of carbon.

Finally, we shall determine the mass of carbon in 16.55 g of glucose. This can be obtained as follow:

180 g of glucose contains 72 g of carbon.

Therefore, 16.55 g of glucose will contain = (16.55 × 72)/180 = 6.62 g of carbon.

Thus, 16.55 g of glucose contains 6.62 g of carbon.
