1. There are 42 grams of sugar (C12H22O11) in a can of pop (342mL). Use this information (where necessary) to answer the following questions:

a) How many moles of sugar are there in the pop (3 marks)?

b) If a mole of sugar costs 90 cents, what is the value of the sugar in a can of pop (3 marks)?

c) How many particles of sugar are there in the pop (3 marks)?

The mole is used to describe the amount of substance. The idea was first introduced by Professor Avogadro and the number of particles that constitute one mole of a substance was said to be 6.02 * 10^23 particles in a mole.

Thus;

Molar mass of sugar = 342 g/mol

Number of moles of sugar = 42 grams/342 g/mol = 0.123 moles

Now;

If 1 mole of sugar costs 90 cents

0.123 moles of sugar costs 0.123 moles * 90 cents/1 mole

= 11 cents

Now we know that;

1 mole of sugar contains 6.02 * 10^23 particles

0.123 moles of sugar contains 0.123 moles * 6.02 * 10^23 particles / 1 mole

= 7.4 * 10^22 particles
