Question

conver into mole(a) 12g of oxygen gas​

Answer 1

N=Given mass/molar mass
N=12/32=3/8moles

Answer 2

Answer:

0.375 moles.

Explanation:

Given :

Given mass is 12 g .

Molar mass of O₂ gas is 32 g .

We have to find numbers of moles or convert into moles .

We know :

Numbers of moles =  Given mass / Molar mass

Putting the values here we get

Numbers of moles =  12 g / 32 g

Numbers of moles =  12 / 32  = 6 / 16

Numbers of moles = 3 / 8

In decimal value is 0.375 moles.

Hence we get 0.375 moles answer .
