<u>Answer:</u> The number of moles of strontium bicarbonate is 
<u>Explanation:</u>
Formula units are defined as lowest whole number ratio of ions in an ionic compound. It is calculate by multiplying the number of moles by Avogadro's number which is 
We are given:
Number of formula units of 
As,
number of formula units are contained in 1 mole of a substance.
So,
number of formula units will be contained in =
of strontium bicarbonate.
Hence, the number of moles of strontium bicarbonate is
