Explanation :

Formula unit : it is defined as the lowest number ratio of ions of an elements in an ionic compound or covalent compound.

For the formula unit of Sr & Cl, two chloride ions(Cl^-) are needed to neutralize the one strontium ion(Sr^{2+}).

For the formula unit of Al & S, three sulfide ions(S^{2-}) are needed to neutralize the two aluminium ion(Al^{3+}).

The formula unit of SrCl_2 and Al_2S_3 are shown below.

Why must the mass of magnesium be less than 0.09 g?
SVEN [57.7K]
The mass of magnesium should be less than 0.09g to enable a faster reaction rate. Magnesium reacts to form a white coating around it which stops the reaction. The lesser the gram the faster the reaction before the coating is formed. It is also advisable to use magnesium fillings to increase the rate of reaction.
