A mole is how scientists quantify a quantity of material, which is important when dealing with several molecules interacting at the same time (i.e. any reaction). The number of atoms in 12 grams of carbon-12 was defined as a mole (an isotope of carbon). And what is the total mass in grams of 0.75 moles of so2?
We know that the number of moles equals the mass supplied (m) / the Molecular Mass.
In this case, 0.75 = m/64 => m = 64×0.75 = 48gm
As a result, the total mass is 48gms.
So one mole of SO2 is equal to 64.063 grams.
Furthermore, 0.75 mole is 0.75 x 64.063 = 48.047 grams.
Oxygen R. A. M.: 16
Total gram weight: 32 + 16*2 = 64g
SO2 0.75: 75/100* 64 = 48g
0.75 number of moles
The number of moles equals the reacting mass divided by the molar mass.
Moles and molar mass, too…!!
You may also calculate compound molar mass from mass numbers…
The following formula: n = mass in grams/molar mass
Also written: mass in g = n molar mass
Putting the values together…
gram mass=0.75 ×64
Due to binding energy, some mass is lost as atoms link to each other, and the more double or triple bonds a molecule has, the lighter it is in compared to the sum of the individual elements.
However, for our purposes here,
The MW of oxygen is 16 grams per mole.
The MW of sulfur is 32 grams per mole.
As a result, SO2 has a MW of 64 g/mol.
Taking 0.75 moles X 64 g/mol = 48 g of SO2 as an example
The crucial thing to remember here is how this is acquired. Take note of the units. If you can remember simple statements like “molecular weight has units of grams per mole,” for example, for all of the main variables in chemistry, it will come in handy when issues like the one you presented occur.
Because you already know how to solve it, all that remains is for you to determine the right value of the units at that time.
Sulfur dioxide (SO2) has a molar mass of 64.07 g/mol. We can now determine the mass in grams using the molar mass.
48 grams in mass
To convert mole quantities to grams, you must go through three stages.
Determine the number of moles stated in the question.
Determine the substance’s molar mass.
Multiply both values together.
Using the Periodic Table, calculate the atomic mass of each element. To calculate the molecular mass, multiply the subscript (number of atoms) by the atomic mass of that element and sum the masses of all the elements in the molecule.
As a result, if there are 0.75mol, the mass is 0.75mol 64.07gmol1 48g.
