WebKOH contains only one K, so a mole of KOH contains one mole of K. How many atoms of K are in 1 mole of KOH? There are 6.022 × 10 23 atoms of potassium in every mole of … WebThree $\ce {O}$ atoms Figure 1: we have one $\ce {Mg}$, two $\ce {N}$ ( $2 \times 1$) and six $\ce {O}$ ( $2 \times 3$) in $\ce {Mg (NO3)2}$. Now all you need is to know that 1 mole equals $6.022\,140\,76\times 10^ {23} \approx 6.022 \times 10^ {23}$ particles . Just multiply: How many Mg atoms are in 5.7892 mol of $\ce {Mg (NO3)2}$?
