Excess silver(I) nitrate was added to a 8.500 g mixture containing some amount of barium chloride, and 7.123 g of silver chlorid
dsp73

Answer:

60.88%

Explanation:

The balanced equation of the reaction is given as;

2 AgNO3 (aq) + BaCl2 (aq) → 2 AgCl (s) + Ba(NO3)2 (aq)

Since AgNO3 is in excess, the limiting reactant is BaCl2. From the reaction;

1 mol of BaCl2 produces 2 mol of AgCl

Converting to masses;

Mass = Number of mol * Molar mass

BaCl2;

Mass = 1 * 208.23 g/mol = 208.23 g

AgCl;

Mass = 2 * 143.32 g/mol = 286.64 g

208.23 g BaCl2 produces 286.64 g of AgCl

x g BaCl2 produces 7.123 g of AgCl

Solving for x;

x = 7.123 * 208.23 / 286.64 = 5.1745 g

Mass percent = Mass / Total mass of Mixture  * 100

Mass Percent = 5.1745 / 8.500 = 0.6088 * 100 = 60.88%

Acetic acid weighs 60g contains 40% carbon, 6.67% hydrogen, and 55.33% oxygen. Calculate it’s molecular formula.
nignag [31]

C₂H₄O₂ is the molecular formula of acetic acid

Explanation:

Acetic acid have a molecular wight of 60 g/mol.

The correct mass percentages for acetic acid are 40% carbon, 6.67% hydrogen and 53.33 % oxygen.

To find the molecular formula knowing the elements mass percentages we use the following algorithm:

we divide each percentage by the atomic weight of the element

for carbon 40 / 12 = 3.33

for hydrogen 6.67 / 1 = 6.67

for oxygen 53.33 / 16 = 3.33

now we divide each value obtained by the smallest value, which is 3.33

for carbon 3.33 / 3.33 = 1

for hydrogen 6.67 / 3.33= 2

for oxygen 3.33 / 3.33 = 1

empirical formula for acetic acid is CH₂O

molecular formula for acetic acid is (CH₂O)ₓ

30x g/mol = 60 g/mol (given by the problem)

x = 2

so the molecular formula for acetic acid is C₂H₄O₂
