Do) 17. A compound containins 27.3 grams of carbon and 72.7 grams of oxygen. Which
of the following is a possible molecular formula?
D
CLE

The possible molecular formula will be

Explanation:

Mass of C= 27.3 g

Mass of O = 72.7 g

Step 1 : convert given masses into moles.

Moles of C =

Moles of O =

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C =

For O =

The ratio of C : O = 1: 2

Hence the empirical formula is

The possible molecular formula will be=

the correct answer would be d. hope this !

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
