## How many moles of O2 are in 50 grams of O2?

To calculate the weight of an element in grams to moles, we should know the molar mass of an element. For example, 50 grams of oxygen is equal to 3 moles.

## How many moles are in O2?

One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

## How many grams of O2 are in 1 mole of O2?

The molar mass from the periodic table is 32.00 g O2 = 1 mol O2, and by definition, 1 mol O2 = 6.02 × 1023 molecules O2. Thus, the two pairs of unit factors are shown in Step 3.

## How many number of moles are there in 50 gram of water?

Answer: The number of moles in 50gm of Water (H20) is 2.77 moles.

## How many moles of O2 are in 48 g O2?
