Ok, lets start off by thinking how many atoms of hydrogen would be in one molecule of C4H10? In one mole of CH4 there are 4 moles of hydrogen atoms, so in 1.25 moles there are (1.25 x 4) 5 moles of hydrogen atoms. One mole of hydrogen would mean there are 6.022 × 10 23 atoms of hydrogen. Likewise, the six hydrogen atoms in ethane are equivalent (Figure 20.2) and removing any one of these hydrogen atoms produces an ethyl group. Implied block. D) carbon, hydrogen, and oxygen.

ONE molecule of butane has the chemical formula of C4H10, so times those numbers by 5 for the 5 molecules, and you should get C20H50. 12. 5) Alkenes and alkynes are called unsaturated compounds because A) they have the maximum number of hydrogen atoms attached to each carbon in the compound. Hydrogen (1) x 10. Now number of moles of CH_4 in 5.2 xx10^24 molecules is =(5.2 xx10^24)/"Avogadro's number" So the number of moles of H atom in it =(4xx5.2 xx10^24)/"Avogadro's number" =(4xx5.2 xx10^24)/(6.024xx10^23)~~34.5mol atom If C = 2, then H = 6.
