If 1 gram of carbon contains x atoms, what will be the number of atoms in 1 gram of magnesium?
In a compound of magnesium (Mg = 24) and nitrogen (N= 14 ), 18 g of magnesium combines with 7 g of nitrogen. Deduce the simplest formula by answering the following questions: (a) how many gram atoms of magnesium are equal to 18 g? (b) how many grams atoms of nitrogen equal to 7 g of nitrogen? (c) calculate simple ratio of gram atoms of magnesium to gram atoms of nitrogen and hence the simplest formula of the compound formed.
What is the number of atoms present in 4.25 grams of NH3 is approximately??
