Why do cold blooded animals go for hibernation?​

because there bllods are cold and if the stay for winter they will die because there blood will become ice or something

because they cannot keep their body temperature constant.

Empirical formula is CH₃.

Explanation:

Given data:

Mass of carbon = 120 g

Mass of hydrogen = 30.3 g

Empirical formula = ?

Solution:

Number of gram atoms of C = 120 g / 12 g/mol = 10

Number of gram atoms of H = 30.3 g / 1.008 g/mol = 30.06

Atomic ratio:

                   C             :            H            

                10/10          :       30.06/10

                   1              :            3.06    

C : H  = 1 : 3

Empirical formula is CH₃.
