Question

find the empirical & molecular formula for the
Compound which contains 45.71%, 10.48%,
13,30% of carbon, hydrogen & Nitrogen, the
rest of the percentage is Oxygen. Molar mass of
compound 210 g/mole​

Answer 1

Answer:

I don't not. ..........answer

Answer 2

Answer:

C4H12NO2

Explanation:

Step 1

Divide the percentage of each element by its atomic no.

*The answer will be mole of that element.*

Step 2

Divide all the moles by the smallest mole to get a ratio.

Theanwer you get is the ratio

For eg,

Moles of C =45.71/12

=3.80

The smallest no. is the mole of N = 0.95

(step2)

3.80/0.95=4

In the same way find the ratios of all the elements
