Find the formula mass (molecular mass) of propanol: C3H6O ​
malfutka [58]

Answer:

                     Formula mass  =  58.09 g

Explanation:

                    Formula mass of a given molecule is defined as the sum of atomic masses of elements forming the empirical formula of that molecule.

                     In order to calculate the formula mass of propanol, following data is required;

Empirical Formula of Propanol:

                                                   The empirical formula of Propanol is C₃H₆O (also the molecular formula) as it is the lowest possible atomic ratio of the given elements.

Atomic Masses of Elements:

                      Carbon  =  12.01 g/mol

                      Hydrogen  =  1.01 g/mol

                      Oxygen  =  16.00 g/mol

Hence,

Formula mass  = (At. mass of C)₃ + (At. mass of H)₆ + (At. mass of O)

Formula mass  = (12.01)₃ + (1.01)₆ + (16.00)

Formula mass  =  36.03 + 6.06 + 16.00

Formula mass  =  58.09 g

What is 2n^2 rule ( of science)​
lozanna [386]

2n² rule:

This rule is used to determine number of electrons in particular shell.

n=1 means K shell

n=2 means L shell

n=3 means M shell

n=4means N shell

The first K shell can hold upto 2 electrons, L shell can hold up to 8, third M shell can hold up to 18and the fourth N shell can hold upto 32 electrons. This rule of arrangement of electrons according to the shell is known 2n2 rule where n means number of shell.

For example: There is one proton in the nucleus of hydrogen atom, which moves in K shell path. It has no neutron.
