Answer:
The mass of CO22 in total is 264 g.
The atomic mass for C is 12 g / mole.
The molar mass for CO22 is (12 + (2 × 16)) = 44 g / mole.
m C = (12 / 44) × 264 = 72 g
So, there are 72 g of C in 264 g of CO2
Explanation:
there's the answer have a good day.
Answer:
Correct option is B. It shows the ratio of elements in the compound.
Explanation:
Empirical formula is the simplest form of the chemical formula. It shows the simplest ratio of atoms in compounds. It is determined by %age of each element.
Explanation:
Using the Combined Gas Law, which is:
<em>(With </em>
<em>being initial pressure, volume and temperature; and</em>
<em />
<em> being the new values)</em>
<em />
We can move the units around in order to solve for 
, which would look like this:
Then we convert the Celsius temperature to Kelvin:
°
= 
° = 
And now, we plug in all of the values and solve, with volume remaining as a constant:
<em>or </em>
Propylethylene would be the answer
For this problem, assume ideal gas then we use the Combined Gas Law.
P₁V₁/T₁ + P₂V₂/T₂ = PV/T
where P, V and T are the total pressure, volume and temperature
Since temperature is kept constant, the equation is simplified to:
P₁V₁ + P₂V₂ = PV
(3.5 atm)(2L) + (2.6 atm)(1.5 L) = (P)(7 L)
Solving for P,
<em>P = 1.56 atm</em>
