Determine the empirical formula of a compound containing 47.37 grams of carbon, 10.59 grams of hydrogen, and 42.04 grams of oxyg

en.
In an experiment, the molar mass of the compound was determined to be 228.276 g/mol. What is the molecular formula of the compound?

For both questions, show your work or explain how you determined the formulas by giving specific values used in calculations.

Okay so the trick is to find the number of moles of each compound you have:

Carbon: 47.37 g / (12.01 g/mol)  = 3.944

Hydrogen: 10.59/1.008 = 10.55

Oxygen: 42.04/16  = 2.6275

Now divide each my the smallest mole number which is oxygen.

3.944/2.6275 = 1.5

10.55/2.6275 = 4

2.6275/2.6275 = 1

So the integer ratio between C:H:O is 3:8:2.

That means the empirical fomrula of the compound is C3H8O2.

However, for the molecular formula, we have to look at the Molar Mass value given. since C3H8O2 has a molar mass of 12.01*3 + 1.008*8 + 16*2 = 76.094,

we can do 228.276/76.084 = 3. So that means the molecular formula of the compound is C9H24O6

Lack of water may prevent the construction of a geothermal energy facility in a particular area because <span>water is used as steam to turn turbines.
</span>These turbines are turned by the power of water and in turn, they produce geothermal energy in these facilities. Without water, these operations wouldn't be able to occur. The saltiness of water, as well as mineral wastes dissolution, and the lack of heat of turbines don't really fit here as an answer.

Think about the lab procedure you just read. Label each factor below with V for “variable” or C for “constant”.
luda_lava [24]
<h2>Answer:</h2><h3>The temperature of the gas: V</h3>

The temperature of gas is a variable quantity. It can be changed by changing energy or pressure of gas.

<h3>The amount of gas in the tube (in terms of mass and moles): C</h3>

It is a constant entity. As mass of gas once taken can not be changed by changing temperature, pressure etc.

<h3>The radius of the tube: C</h3>

The radius of tube cannot change at any rate.

<h3>The temperature of the gas (changed by the water surrounding it):  V</h3>

It can be changed by changing the temperature of water surrounding it.

<h3>The type of gas: C</h3>

It can never be changed.

<h3>The pressure of the gas: V</h3>

It can be changed by simply changing temperature and volume of gas.
