Complete combustion of 3.20g of a hydrocarbon produced 9.69g of CO2 and 4.96g of H2O. What is the empirical formula for the hydr

vlabodo [156]

Let empirical formula for hydrocarbon is CxHy

it will undergo combustion as

CxHy + (x + y/4) O2 ---> xCO2 + (y/2 )H2O

Given that mass of CO2 produced = 9.69 g

So moles of CO2 produced = 9.69 / 44 = 0.22 moles

So moles of carbon present = 0.22 moles

mass of H2O produced = 4.96 g

Moles of H2O produced = mass / molar mass = 4.96 / 18 = 0.28 moles

So moles of H present = 2 X 0.28 = 0.56 moles

Let us divided the moles of each with lowest value of moles

Moles of Carbon = 0.22 / 0.22 = 1 moles

moles of H = 0.56 / 0.22 = 2.55

Multiplying with two to get whole number

the ratio of carbon and hydrogen will be : C:H = 2:5

empirical formula : C2H5

3. Calculate the volume, in mL, of 100.0 g of alcohol, if the density is 0.79 g/mL.

Naya [18.7K]

Answer:

The answer is

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

<h3> $volume = \frac{mass}{density}$ </h3>

From the question

mass of alcohol = 100 g

density = 0.79 g/mL

The volume is

$volume = \frac{100}{0.79} \\ = 126.58227848...$

We have the final answer as

Hope this helps you
