Question

Mass of 48.176*10²³ molecules of methane will be?

Answer 1

given moles = 48.176*10^23/6.022*10^23 = 8 moles
mass of 8 moles methane = 8*(molecular mass of methane)=8*16=128...

Answer 2

Hey Guys,

Given Molecules =48.176 ×10*23
Avogadro's No. of in 1 atomic mass unit =6.022×10*23

Mass of Molecules of Methane = 48.176×10*23/6.022×10*23= 8u (Mass of Methane )

Thanks .
