Answer : The number of grams of calcium perchlorate is, 0.00253 grams.

Explanation :

Molar mass of calcium perchlorate = 238.9 g/mol

As, 6.022\times 10^{23} formula units present in 238.9 g of calcium perchlorate

So, 6.37\times 10^{18} formula units present in \frac{6.37\times 10^{18}}{6.022\times 10^{23}}\times 238.9=0.00253g of calcium perchlorate

Therefore, the number of grams of calcium perchlorate is, 0.00253 grams.

Justify air is a mixture not a compound
Andreas93 [3]
A compound has to be chemically bonded, however, air is not chemically bonded.
This can be proven by freezing air. By freezing air, it yields different liquids at different temperature. Liquid nitrogen has a different boiling point than liquid oxygen.
If air was a compound, they would all have a single boiling point and a single freezing point.


Hope this helps :)
