Question

if a compound possesses 40 point 83 gram carbon 2.38 hydrogen 16.66 gram nitrogen and 38.07 gram oxygen which of the following will be its empirical formula​

Answer 1

Answer:

To find the empirical formula change the mass to moles Then find a ratio between the moles.

For Carbon

38.8

12

=

3.233

moles

For Hydrogen

16.2

1

=

16.2

moles

For Nitrogen

45.1

14

=

3.22

moles.

The ratio for Carbon and Nitrogen is

1

:

1

3.233

3.22

=

1.00

The ratio of Hydrogen to both Carbon and Nitrogen is 5:1

16.2

3.22

=

5.03

So the ratio is 1 C to 1 N to 5 H.
