The student puts a teaspoon (10 g) of C12H22O11 sugar in a cup of tea. How many sugar molecules does a student drink along with this tea?

1.76 x 10²²molecucles

Explanation:

Given parameters:

Mass of the sugar  C₁₂H₂₂O₁₁  = 10g

Unknown:

Number of molecules  = ?

Solution:

The number of molecules can be determined if we find the number of moles first.

  Number of moles  =  

  Molar mass of C₁₂H₂₂O₁₁ = 12(12) + 22(1) + 11(16) = 342g/mol

 Number of moles  =   = 0.029mole

1 mole of C₁₂H₂₂O₁₁ will contain 6.02 x 10²³

  0.029 mole of C₁₂H₂₂O₁₁ will be made up of 0.029 x 6.02 x 10²³

                         = 1.76 x 10²²molecucles

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
