Help calculating molar mass

Chemistry
1 answer:
Irina-Kira [14]3 years ago
7 0
Molar mass can be determined by adding the atomic masses of each individual element, depending on how many times they appear. You can find how many times they appear by looking at their respective subscripts. Atomic masses of each element can be found on the periodic table.

For example, in #1

Multiply the mass of Lithium (6.941) by 4, because there are 4 lithium molecules.

Multiple the mass of Phosphorus (30.974) by 2 because there are 2 Phosphorus molecules.

And multiply the mass of oxygen (15.999) by 7 because there are 7 oxygen molecules.

After you have those values, add them together to find the total molar mass of the compound.

the company calculated that they would produce 4.8 tonnes of magnesium but only 3.2 tonnes was produced calculate the percentage
Aneli [31]
To find the percentage yield you must take the actual yield and divide it by the theoretical yield and times it by 100. (Percent yield=Actual/Theoretical * 100)
For this example the calculated (Theoretical value) was 4.8 tones and the tones produced (Actual value) was 3.2 tones.
So 3.2/4.8 *100 = 66.6666666….
