The percentage composition of acetic acid is found to be 39.9% C, 6.7% H, and 53.4% O. What is the empirical formula of acetic a
anastassius [24]

Answer:

CH₂O

Explanation:

From the question given above, the following data were obtained:

Carbon (C) = 39.9%

Hydrogen (H) = 6.7%

Oxygen (O) = 53.4%

Empirical formula =?

The empirical formula of acetic acid can be obtained as follow:

C = 39.9%

H = 6.7%

O = 53.4%

Divide by their molar mass

C = 39.9 / 12 = 3.3

H = 6.7 / 1 = 6.7

O = 53.4 / 16 = 3.3

Divide by the smallest

C = 3.3 / 3.3 = 1

H = 6.7 / 3.3 = 2

O = 3.3 / 3.3 = 1

The empirical formula => CH₂O

The world's total petroleum reserve is estimated at 2.0 x 10^22 joules La joule (J) is the unit of energy where 1J =1kg m^2/s^2)
mamaluj [8]

Answer:

It will take 1.1\times 10^{2}years to exhaust the supply

Explanation:

We have to apply unitary method to solve this problem.

Divide total petroleum reserve by petroleum consumption in each year to calculate estimated time.

Presently, 1.8\times 10^{20} joules of petroleum are being consumed per year.

Hence, applying unitary method, 2.0\times 10^{22} joules of petroleum can be consumed in \frac{2.0\times 10^{22}}{1.8\times 10^{20}}years=1.1\times 10^{2}years
