1 mol of K = 39.10 g so 1 mol of K2 = 78.20 g
1 mol of O = 16.00 g
1 mol of K2O = 94.20 g
1 mol = 94.20 g
0.436 mol = ? g
? = 41.07 g
The ionic compound of K2O is potassium oxide. It is formed from the combination of potassium (K) cations and oxide (O) anions. Its chemical formula is K2O.
K2O is potassium oxide
The balanced equation is 2HCl + K2O -> H2O + 2KCl.
potassium oxide
The ionic compound K2O is called potassium oxide. It is composed of potassium cations (K+) and oxide anions (O2-).
According to the reaction (4 \text{K} + \text{O}_2 \rightarrow 2 \text{K}_2\text{O}), 4 moles of potassium produce 2 moles of potassium oxide (K2O). Thus, the mole ratio of potassium to K2O is 4:2, or 2:1. If 1.52 moles of potassium are used, the number of moles of K2O formed can be calculated as (1.52 , \text{moles K} \times \frac{2 , \text{moles K2O}}{4 , \text{moles K}} = 0.76 , \text{moles K2O}). Therefore, 0.76 moles of potassium oxide will be formed.
6.022 x 1023 formula units of K2O are equal to one mole of K2O.
This mass is 631,75 g K2O.
