We assume you are converting between moles Oxygen and gram. You can view more details on each measurement unit: molecular weight of Oxygen or grams The molecular formula for Oxygen is O. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Oxygen, or 15.9994 grams.
There are 80 gram of oxygen molecule present in 2.5 moles of [tex]O_{2}[/tex] molecule.
What is moles?
The mole (sign mol) is just the SI base unit of material quantity. The amount of substance in an object is a measurement of how many elementary units of a certain substance are present.
It can be represented as:
Moles = mass / molar mass
Calculation of mass of oxygen by using moles formula:
Given data:
Moles = 2.5
Mass = ?
Molar mass = 32.
Put the value of given data in moles formula:
Mass = moles × molar mass
Mass = 2.5 × 32
Mass = 80 gram
Therefore, there are 80 gram of oxygen molecule present in 2.5 moles of [tex]O_{2}[/tex] molecule.
