Answer

Answer:

1.5, 23

Explanation:

Step1: Recall the conversion factor

1 mole = $6.02\times10^{23}$ formula - units

Step2: Calculate the number of formula - units

Number of formula - units = moles $\times$ Avogadro's number. Given moles = 0.25 mol. So, number of formula - units = $0.25\times6.02\times10^{23}=1.505\times10^{23}$. The coefficient is 1.5 and the exponent is 23.
