In 'MgO', If O = 1.725 mole, then how to calculate the mole of Mg?
« Reply #31 on: August 25, 2018, 09:46:25 PM »
Say, MgO is a compound. In this compound oxygen is 27.6%. If the total compound is 100g, If I want to calculate the moles of oxygen, that would be
16g O weigh 1 mole of O So, 27.6g O weighs 1.725 moles of O.
Now my second question is that If I want to count the mole of Mg. You would say that Mg is also 1.725 moles. but how in MgO if O = 1.725 moles, then why Mg is also 1.725 moles? I am confused here. Please explain. Please don't lock my thread in this topic. Please help me understand the concept.

@IBM
I have combined the entries that are similar.
Making multiple entries that are alike is confusing.
