Iodine dissolves easily in chloroform and hexane but does not dissolve in water. When polar and non-polar are mixed, water finds other water and forms spherical bubbles. When mixed with hexane, the iodine molecules experience London dispersion forces. There is no induced polarity in the iodine molecules and they exhibit their typical violet color in the solution. (Note: The color may be pink if the iodine concentration is low.) Hope this helps!!
Answer is: there are 5,275·10²³ hydrogen atoms in methane.
m(CH₄) = 3,50 g.
n(CH₄) = m(CH₄) ÷ M(CH₄).
n(CH₄) = 3,5 g ÷ 16 g/mol.
n(CH₄) = 0,219 mol.
n(CH₄) : n(H) = 1 : 4.
n(H) = 4 · 0,219 mol = 0,876 mol.
N(H) = n(H) · Na.
N(H) = 0,876 mol · 6,022·10²³ 1/mol.
N(H) = 5,275·10²³.
Na - Avogadro number.
