Question

100 grams of methane. Find the number of atoms

Answer 1

Answer:

Mass given of methane = 100 g

Molar Mass of methane, Ch4 = 12 + 4 = 16 g

Given Mass / Molar Mass = Number of atoms / Avagadro number

6.25 × 6.022 ×10^23 = Number of atoms

Number of atoms = 37.64 × 10^23

Answer 2

Answer:

Explanation:

Given data:

mass of methane=100 grams

To find out:

Number of atoms=?

Solution:

Formula being used here:

Number of atoms= Given mass/molar mass * Avogadro's number

Molar mass of methane is 16 gram.

Putting values:

Number of atoms= 100/16 * 6.02 * 10^23

                            =37.625 * 10^23 atoms of methane

Number of atoms of methane in 100 grams are 37.625 * 10^23 .

HAVE A GREAT DAY MATE :)
