Question

Calculate the mass of methane which contains 2.4 ×10^24atoms of hydrogen

Answer 1

Answer:

Explanation:

$CH_4=C+4H\\\\4H=1C\\\\2.4\times10^{24}H=xC\\\\x=6\times 10^{23}atoms\\\\1 mole\; of\; C \;contains( 6\; \; \times 10^{23})atoms=12grams\\\\1 mole \;of\;hydrogen\;contains\;6\times 10^{23}atoms=1gram\\\\here \;4H=2.4\times 10^{24}atoms={4}\times6\times 10^{23}atoms=4grams\\\\therefore mass of methane\\\\=C+4H\\\\=12+4\\\\=16grams$
