Question

Calculate the mass of 2.5 gram molecular of oxygen

Answer 1

Answer:

mass of ur given question is 16into 2.5 i. e. 40 is ur ans

Answer 2

Molecular mass of oxygen (O2)= 32 g

Given mass = 2.5 g

So the molecular mass of 2.5 g of oxygen = Given Mass / Molecular Mass = 2.5 / 32 = 0.078 g

The required mass is 0.078 g.

What is oxygen ?

Oxygen is an element that is a non metal.

It's atomic number is 8 while it's atomic mass is 16.
