How many grams of sulfur trioxide are produced 18 mol O2 react with sufficient sulfur? Show all your work S8 +12O 2> 8SO3

SOVA2 [1]

Answer:

$m_{SO_3}=2.31x10^4gSO_3$

Explanation:

Hello!

In this case, since the reaction between sulfur and oxygen is:

$S_8 +\frac{1}{2} O_2 \rightarrow 8SO_3$

Whereas there is a 1/2:8 mole ratio between oxygen and SO3, and we can compute the produced grams of product as shown below:

$m_{SO_3}=18molO_2*\frac{8molSO_3}{1/2molO_2} *\frac{80.06gSO_3}{1molSO_3} \\\\m_{SO_3}=23,057.3gSO_3=2.31x10^4gSO_3$

Best regards!

What is the molarity if a solution that contains 289 grams of sugar in a 2 liter solution?? Molar mass of source is 342.2965g/mo

Olegator [25]

<u>Answer;</u>

= 0.422 M

<h3><u>Explanation;</u></h3>

Molarity or concentration is the number of moles of a solute in 1 liter of a solution.

Therefore; Molarity = n/V ; where n is the number of moles and V is the volume of the solution in L.

Number of moles = Mass/molar mass

= 289 g/342.2965g/mol

= 0.844 Moles

Therefore;

Molarity = 0.844 moles/ 2L

= 0.422 M

why would a can of soda fizz much more when opened on top of Mt. Everest than when opened at sea level?

Gelneren [198K]

This would happen because the pressure on Mt.Everest is much more higher than the pressure at sea level, the can would probably be swollen so to this too.
