Find the formula mass (molecular mass) of propanol: C3H6O

                     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

i believe it is a.) released into

explanation:

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
