28 g
1 gram atom of nitrogen = 14 g
4 gram atoms = 4 × 14 = 56 g
The weight of 4-gram atoms of nitrogen is
The weight of 4gram atoms of nitrogen is
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.
