Answer:
Answer in explanation
Explanation:
An atom of iron having an atomic number of 26 means there are 26 protons in the nucleus of the iron atom. This also means that for an electrically neutral atom of iron, there are 26 electrons orbiting the nucleus of the iron atom.
Factually, this also means that the atom iron occupies the position of the 26th element on the periodic table. Going forward, we can also say that the proton number of the iron element is 26.
0.05 mol of oxygen atom.
Explanation:
Mass of potassium hydroxide = 2.79g
Unknown:
Number of moles = ?
Solution:
To solve this problem, find the number of moles of the potassium hydroxide.
Number of moles of KOH =
Molar mass of KOH = 39 + 16 + 1 = 56g/mol
Number of moles of KOH = = 0.05mole
Now,
1 mole of KOH contains 1 mole of oxygen atom
0.05 mole of KOH will have 0.05 mole of oxygen atom.
