<u>Answer:</u> The mass of given amount of molecules of copper sulfate is 89.054 grams.

<u>Explanation:</u>

According to mole concept:

1 mole of a compound contains 6.022\times 10^{23} number of molecules.

The mass of 1 mole of copper sulfate = 159.609 grams

As, 6.022\times 10^[23} number of molecules have a mass of 159.609 grams.

So, 3.36\times 10^{23} number of molecules will have a mass of \frac{159.609g}{6.022\times 10^{23}}\times 3.36\times 10^{23}=89.054g

Thus, the mass of given amount of molecules of copper sulfate is 89.054 grams.

Molar mass of cuso4=63.5+32+4*16= 159.5 g
6.02*10^23 molecules weigh=159.5 g
1 molecule weigh=159.5/6.02*10^23 g
3.36 × 10^23 molecules weigh=159.5/6.02*10^23*3.36× 10^23
=89.023g

The complete combustion of a sample of propane produced 2.641 grams of carbon dioxide and 1.442 grams of water as the only produ
ohaa [14]
A general equation for a combustion reaction would be expressed as follows:

CxHy + (x+y/2)O2 = xCO2 + y/2H2O

Propane would obviously would only have carbon and hydrogen in its structure. Assuming a complete combustion, all of the carbon atoms would go to carbon dioxide and all of the hydrogen atoms to water. To determine the empirical, we determine the number of carbon and hydrogen atoms present.

moles C = 2.461 g CO2 ( 1 mol / 44.01 g ) ( 1 mol C / 1 mol CO2 ) = 0.06 mol C

moles H = 1.442 g H2O ( 1 mol / 18.02 g ) ( 2 mol H / 1 mol H ) = 0.16 mol H

Then, we divide the smallest amount to the each mole of the atoms. We do as follows:

C = 0.06 / 0.06 = 1
H = 0.16 / 0.06 = 2.67

Then we multiply a number in order to obtain a whole number ratio between the atoms.
