Calculate the percentage of limestone that dissolved from each solution. Start by subtracting the final mass from the initial ma
ss. Divide that number by the initial mass. Then multiply the result by 100 to make it a percent. Use this formula:
% dissolved= initial mass- final mass/ initial mass x 100
ORIGINAL: 0% Acid 33% Acid 66% Acid 100% Acid
Initial Mass (g) 10.0 10.1 10.0 9.9
Final Mass (g) 10.0 10.0 9.8 9.5
Record the percentage of limestone dissolved in each acid concentration.

Explanation:
It works nicely to let a spreadsheet do the calculations described in your problem statement.
You don't actually have to multiply by 100 to make the number a percent. Spreadsheets have the capability to show a value as a percentage just by changing the format.

Answer:
There are 10.0 moles of beryllium oxide in a 250 grams sample of the compound.
Explanation:
We can calculate the number of moles (η) of BeO as follows:
Where:
m: is the mass = 250 g
M: is the molar mass = 25.0116 g/mol
Hence, the number of moles is:
Therefore, there are 10.0 moles of beryllium oxide in a 250 grams sample of the compound.
