Question

Convert 10g of oxygen gas into no. of moles.

Answer 1

Given, mass of oxygen gas = 10g.

Relative Molecular mass of oxygen gas ($O_{2}$) = 32 g.

Therefore, No. of moles = $\frac{GivenMass}{RelativeMolecularMass}$
                                       = (10/32) g
                                       = 0.3125 g
 
  

Answer 2

Answer:

Explanation:

number of moles = weight ÷ GMW

so the answer is 10/32

this gives the answer which equals to 0.3125
