Question

calculate the mass of 10²² molecules of CH4​

Answer 1

Answer:

0.265g

Explanation:

Use this formula,

no. of molecule/6.023×10^23=weight of CH4/molecular mass of CH4,because

we know that-

mole=no. of molecule/6.023×10^23 again ,,

mole =mass /molecular mass

So, from equation 1&2 we get this formula ....
