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

A 50 L cylinder is filled with argon gas to a pressure of 10130.0 kPa at 300°C. How many moles of argon gas does the cylinder co
Vlad1618 [11]
To answer this question, we will use the general gas law which states that:
PV = nRT where:
P is the pressure of the gas = <span>10130.0 kPa
</span>V is the volume of the gas = 50 liters
n is the number of moles that we want to calculate
R is the gas constant = <span>8.314 L∙kPa/K∙mol
T is the temperature = 300+273 = 573 degree kelvin

Substitute with the givens in the equation to get the number of moles as follows:
</span><span>10130 * 50 = n * 8.314 * 573
506500 = 4763.922 n
n = </span>506500 / 4763.922
n = 106.3199 moles
