Answer:
9.24% the percent of Mg in the mixture.
Explanation:
Mass of silver bromide = 1.1739 g
Moles of silver bromide =
1 mole of AgBr has 1 mole of bromine atom.Then 0.006244 moles AgBr has 0.006244 mole bromine atom.
Moles of bromine atoms = 0.006244 moles
Magnesium bromide has 2 moles of bromine atom.Then 0.006244 moles of bromine atoms will be in :
Magnesium bromide has 1 mole magnesium atom, then 0.003122 moles of magnesium bromide will have :
magnesium atom
Mass of 0.003122 moles of magnesium :
0.003122 mol × 24 g/mol = 0.07493 g
Mass of the sample = 0.8107 g
Percentage of magnesium in the sample ;
9.24% the percent of Mg in the mixture.
Answer:
Physical, Inorganic, Biochemistry, Analytical, and Organic
Physical chemistry deals with applying physics to the study of matter. It's also probably the most important branch. Inorganic chemistry deals with stuff that is chemically composed of elements other than carbon. The branch of Biochemistry concerns itself with living things. Analytical chemistry deals with analyzing and finding out what substances are present in a particular material and how much of each substance is present. Finally, organic chemistry deals with substances that are compounds of carbon.
