Answer : The number of formula units of sodium acetate is \(5.2\times 10^{23}\)
Explanation :
Formula units : It is 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 \(6.022\times 10^{23}\)
We are given:
Number of moles of sodium acetate = 0.87 moles
Number of formula units = \(0.87\times 6.022\times 10^{23}=5.2\times 10^{23}\)
Hence, the number of formula units of sodium acetate is \(5.2\times 10^{23}\)
