Question

Example: Sugar (C12H22O11) - Add up the masses of each element. (Look at your periodic table for the masses.)

Please and thank you so much :)!!!!

Answer 1

342.3 g

Step-by-step explanation:

From the question given above, the following data were obtained:

C = 12.011 g/mol

H = 1.00794 g/mol

O = 15.9994 g/mol

Molar mass of C₁₂H₂₂O₁₁ =?

C = 12 × 12.011 = 144.132 g

H = 22 × 1.00794 = 22.17468 g

O = 11 × 15.9994 = 175.9934 g

Total mass = 144.132 + 22.17468 + 175.9934

Total mass = 342.3 g
