Question

calculate the molar mass of a Teflon that contains 5.0x10^4 CF2 units
help me confirm my answer :)

Answer 1

The molar mass of Teflon contains $5\times 10^4$ CF₂ units is  $\boxed{2.5\times 10^6}$

Step-by-step explanation:

Given:

Teflon contains $5\times 10^4$ CF₂ units

To find out:

Molar mass of Teflon

Solution:

We know that Teflon is a polymer which contains repeated -CF₂- chains

According to the question the given Teflon contains $5\times 10^4$ CF₂ units

Molar mass of CF₂ = 12 + 2 × 19 = 12 + 38 = 50

Therefore, molar mass of  $5\times 10^4$ CF₂ units

= $50\times 5\times 10^4$

= $2.5\times 10^6$

Hope this answer is helpful.
