Question

how many moles of chlorine atoms are in 2.25 moles of chloroform

please help me with this

Answer 1

CHCl3 is the formula for chloroform

Look at the percentage atomic mass of chlorine out of the total RFM:
[3*(35.5) / 3*(35.5)+1+12]*100
=89.1% (3s.f)

Then do 89.1% of 2.25 moles
=2.01 moles (3s.f)

This is how i would approach the problem, but just double check to see if its right ^^

Answer 2

CHCl3 is the molecular formula of chloroform -->

Answer 3

@mangotangochick
I don't think that's right. You found the percentage by mass of chlorine in chloroform but the question doesn't ask that...

You can find the moles of chlorine in chloroform by doing a simple dimensional analysis
