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
after a volcanic eruption is the answer
Mudflows of volcanic eruptions are the most dangerous, and are called lahars
Well cars need gas to run on if the car does not have gas it wont run and you cant get to places you need to go only if you have gas.
N=3^K-1 I really don't know how to explain it but that's the formula <span />
Answer:
the size of Ca is the greatest ,then Mg is the greater on size than Be
Explanation:
if you make the electron configuration for each of the elements, what is the main difference u gonna see ?
Be 4 1s2/2s2
Mg 12 1s2 /2s2 2p6/3s2
Ca 20 1s2 /2s2 2p6/3s2 3p6 3d/4s2
see that all the elements are in the same group but are in different period
u gonna see the last electron valance shell in Ca are too far from its nucleus but in Be the last electrons are too close and more attracted to the atom's nucleus , so the size of Ca is the biggest then Mg then Be
