Convert 3.2 moles of ch4 to number of molecules

1.93 x 10^24 molecules

Explanation:

CH4 is the chemical formula for methane, the first member of the alkane family.

Based on Avogadro's law:

1 mole of any substance has 6.02 x 10^23 molecule

So, 1 mole of CH4 = 6.02 x 10^23 molecules

3.2 moles of CH4 = Z

To get the value of Z, cross multiply:

(Z x 1 mole) = (6.02 x 10^23 molecule x 3.2 moles)

Z•mole = 19.26 x 10^23 molecules•mole

Divide both sides by 1 mole

Z•mole / 1 mole = 19.26 x 10^23 molecules•mole/ 1mole

Z = 19.26 x 10^23 molecules

Place Z in standard form

Z = 1.93 x 10^24 molecules

Thus, 3.2 moles of ch4 has 1.93 x 10^24 molecules

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
