262mol 1=kg
g=1000
from stoichoimetry
x=102*1000/360
x=102000/360
x=283.33
density =m/v
=283.33/1.082
=262mol

Answer:
Explanation:
If percentage are given then we are taking total mass is 100 grams.So, the mass of each element is equal to the percentage given.
Mass of Mg = 10.89 g
Mass of Cl = 31.77 g
Mass of O = 57.34 g
Step 1 : convert given masses into moles.
Moles of Mg=
Moles of Cl =
Moles of O =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For Mg =
For Cl =
For O=
The ratio of Mg :Cl : O= 1 : 2 : 8
Hence the empirical formula is
