Convert 12 g of Oxygen Gas into Mole

Convert 12 g of Oxygen gas into mole.

What is a mole?

A mole is referred to as the amount of the substance that is containing exactly 6.02214076  × 1023 molecules of the given substance. A mole of a substance is defined as the mass of a substance that consists of the same number of fundamental units as there are atoms in exactly 12.000 g of 12C.

Conversion of 12 g of oxygen gas into moles

For converting the 12 g of oxygen into a mole, we need to know first the molar mass of that element. Here the element that is given for converting it into mole is Oxygen. We already know that the molar mass of the oxygen is 32. Now according to the mole definition, the molar mass that element has is equal to one mole.  

Now we need to find out the number of moles for 1 gm of the oxygen element by equating the molar mass of the Oxygen element i.e 32 gm equal to 1 mole. The result that will be obtained comes out to be 1/ 32. Now, we can calculate the number of moles for any given weight of the given Oxygen element by just multiplying that given element by 1/32. 

So, here, we want to calculate the number of moles for every 12 gm of the Oxygen element. Therefore, by just multiplying the given weight i.e 12 gm with 1/32, the desired result would come out to be 0.375.

However, we can calculate the number of moles in other ways also, by just simply applying the formula. The formula that is given for calculating the number of moles of any element is equal to weight divided by molar mass. Moles have no unit as we calculate the number of moles by dividing the given weight by molar mass and both of them have the same unit that will get cancelled out and will result in the moles being unitless.
