Calcium chloride is a compound with the formula CaCl₂. A teacher has two samples of calcium chloride, one with a mass of 5 g and one with a mass of 50 g.

What is true about the atoms in these two samples?

[1]
A

The 50 g sample contains a greater proportion of chlorine atoms than the 5 g sample

B

Both samples contain calcium atoms and chlorine atoms in the ratio 1 : 2

C

Both samples contain calcium atoms and chlorine atoms in the ratio 2 : 1

D

Both samples contain calcium atoms and chlorine atoms in the ratio 1 : 1
