Question

Calculate the number of moles in 65.6 microgram of carbon

Answer 1

Step-by-step explanation:

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

Step-by-step explanation:

65.6 micrograms =65.6/10³g

molar mass of C=12g

moles = 65.6÷(10³×12)= 5.47*10^-3mol
