Differences between a mixture and a compound are;
A mixture can be separated by physical means such as decantantion and filtration whereas a compound can only be separated by chemical means like smelting
The proportion of elements in a mixture varies while the proportion of elements in a compound is constant
Elements retain their characteristics in a mixture while in a compound, elements never retain their characteristics
<span>when the number of moles Ca = mass of Ca / molar mass of Ca.
and we can get the molar mass of Ca, it is = 40 g/mol
and we have already the mass of Ca (given) = 9.8 g
so, by substitution: the moles Ca = 9.8 g / 40 g/mol
= 0.245 moles</span>
