Question

7) An organic compe of Carbon, hydrogen and oxygen contain 40. 69 percent of carbon 54.23% of
oxygen the vapour
density of this compound is 59 determine the molecular formula of this compound​

Answer 1

Answer:

10 .2 density is the answer

Answer 2

Answer:

Explanation:

Answer : The molecular formula of the com[pound is,

Solution : Given,

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 C = 40.687 g

Mass of H = 5.085 g

Mass of O = 54.228 g

Molar mass of C = 12 g/mole

Molar mass of H = 1 g/mole

Molar mass of O = 16 g/mole

Step 1 : convert given masses into moles.

Moles of C

Moles of H

Moles of O =

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C

For H

For O

To make the whole number, multiplying the ratio by 2.

The ratio of C : H : O = 2 : 3 : 2

The mole ratio of the element is represented by subscripts in empirical formula.

The Empirical formula

The empirical formula weight = 12(2) + 3(1) + 2(16) = 59 gram/eq

Formula used

Molecular formula

Therefore, the molecular formula of the

What is the vapor pressure of oxygen?

For example, air at sea level, and saturated with water vapor at 20 °C, has partial pressures of about 2.3 kPa of water, 78 kPa of nitrogen, 21 kPa of oxygen and 0.9 kPa of argon, totaling 102.2 kPa, making the basis for standard atmospheric pressure

What is the formula for density?

The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
