Question

Find the number of moles present in 64 GM's of methane is​

Answer 1

moles of methane = Given mass/molar mass = 64/16 = 4. So, there are 4 moles of methane or 4* 6.022 * 10^23 molecules of methane [ one mole has weight as molecular weight in gm] or 10 * 4 * 6.022 *10^23 e in 64 gm of methane [as each molecule has 10e].

Answer 2

Explanation:

moles of the methane=given mass by molar

mass=64/16=4.so there are 4moles of Metheny or 4*6.022*10^23 molecules of methane.
