How do we compute for a mole in a specific substance?



Answer:
a mole is a unit of measurment. one mole of any element contains 6.022*10^23 atoms of that element. the molar weight given for each element on the periodic table represents the weight of one molar unit, or 6.022*10^23 atoms of this element. in order to find the molar weight of a substance you add the molar weight of each element found within the compound. once you have found the molar weight of the substance you determine the weight of the sample. the weight of the sample divided by the molar weight of the substance will determine how many moles are present in the sample
a mole is just a number just like how "dozen" is 12. a mole is 6.02x10^23. So a mole of any substance is 6.02x10^23
