Explanation: i think i’m not sure
A mole corresponds to the mass of a substance that contains particles of the substance.
The concept of moles are used in various ways:-
- Chemical equation.
- Law of constant proportion.
According to the question, the formula required is:-
[tex]n=\frac{Number\ of\ molecules}{na}[/tex]
The Na is defined as the Avogadro constant is the proportionality factor that relates the number of constituent particles in a sample with the amount of substance in that sample.
According to the question, the compound is [tex]Sr(HCO_{3})_{2}[/tex].
