An unknown compound contains only c, h, and o. combustion of 2.90 g of this compound produced 6.59 g of co2 and 2.70 g of h2o.

Given that :

Mass of = 6.59 g

Mass of = 2.7 g

Total mass of compound = 2.9 g

Explanation :

From given data,

Mass of C in 6.59 g =

Mass of H in 2.7 g   =

Mass of O = 2.9-(0.0414+0.0412) = 2.82 g

Moles of each atoms

C =

H =

O =

Simpler ratio of moles for  each atom

C =

H =

O =

According to above given values the possible formula for compound will be

increased stability in the completion of fluorine's outer shell.

girl imma just put my comment here because i need a couple point okurrttt
