Answer:
32.23 to 4 significant figures.
Explanation:
The molar mass of the element is the mass of 6.022 * 10^23 atoms (Avogadro's number).
So by proportion it is 6.022 * 10^23 * 3.88 / 7.25 * 10^22
= 32.23 to 4 significant figures.
Answer:
<h3>The answer is 286.36 cm³</h3>
Explanation:
In order to find the volume be at 101.3 kPa we use Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the final volume
From the question
P1 = 112 kPa = 112000 Pa
V1 = 259 cm³
P2 = 101.3 kPa = 101300 Pa
We have
We have the final answer as
<h3>286.36 cm³</h3>

Answer:
12
Explanation:
The coefficient of the CO2 shows the amount of CO2 needed in the reaction so to react with 11 water, 12 molecules of carbon dioxide is needed.
