Question

Calculate the number of moles in 65.6 ug of carbon

Answer 1

Hey there !

Given mass = 65.6 ц g

1 ц g = 10⁻³ g

Hence Given Mass = 65.6 × 10⁻³ g

Molar Mass of Carbon = 12 g

Number of moles = Given Mass / Molar Mass

=> Number of Moles = ( 65.6 / 12 ) × 10⁻³ 

=> Number of moles = 5.46 × 10⁻³  moles

Hope my answer helped !

Answer 2

Answer:

atomic mass of carbon = 12

1ug= 10^3

given mass =65.6×10^3g

moles of carbon = {mass of carbon ÷ atomic mass }

65.6×10^3 \12

= 5.46 × 10^-3 moles
