Calculate
(a) Mass of `2.5` gram atoms of magnesium,
(b) Gram atoms in `1.4` grams of nitrogen (Atomic mass : `Mg = 24,N=14`)

Text Solution

Verified by Experts

(a) gram atom of `Mg = 24 g`
2.5 gram atoms of `Mg = 24 xx 2.5 = 60` g
(b) 1 gram atom of `N = 14` g ,
`14 g` of `N=1` gram atom
1.4 g of `N=(1)/(14)xx1.4=0.1` gram atom
