How many moles are in 135g of Teflon?

Oliga [24]

1.34 moles are in 135g of Teflon.

Explanation:

Molecular formula of teflon is (C2H4)n

mass of teflon = 135 grams

atomic mass of teflon = 100.01 gram/mole

number of moles of teflon = ?

Formula used to calculate number of moles in a substance is given as:

number of moles = $\frac{mass}{atomic mass of 1 mole}$

putting the values in the above equation:

number of moles = $\frac{135}{100.01}$

number of moles = 1.34 moles

Teflon is polymer which is used for making non-stick coating, in 135 grams of teflon there are 1.34 moles in it.
