A chemistry teacher holds up one mole of table sugar (C12H22011). In the one mole sample there are:
O 6.02 x 1023 molecules of table sugar
O a total of 6.02 x 1023 atoms of carbon, hydrogen and oxygen
O 6.02 x 1023atoms of carbon, 6.02 x 1023 atoms of hydrogen and 6.02 x 1023of oxygen
O All of the above

There are 6.02.10²³ molecules of table sugar

Further explanation

Given

1 mole of table sugar

Required

moles and molecules

Solution

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

1. 6.02.10²³ molecules of table sugar⇒true

2. There are :

12 moles of C = 12 x 6.02.10²³ atoms

22 moles of H = 22 x 6.02.10²³ atoms

11 moles of O = 11 x 6.02.10²³ atoms

A total of6.02.10²³ atoms of carbon, hydrogen and oxygen⇒false

3 and 4 ⇒ false
