2. In a combustion reaction, a sample of carbon dioxide was collected. The following data were reported for properties of this carbon dioxide sample.

GIVEN FIND

Mass = 4.157 g Rexp
P = 856.3 torr
V = 2.498 L
T = 85.6 C

Explanation:

The statement gives some properties of a sample of carbon dioxide collected during the experiment of a combustion reaction and asks to determine the percent deviation of the experiment.

Then, what you must calculate is the percent error on the mass.

That is:

% error = |measured mass - theoretical mass| / (theoretical mass) × 100

The measured mass was 4.157g

The theoretical mass can be calculated from the data of pressure, volume, and temperature, using the ideal gas equation:

Now use the molar mass of CO₂ to calculate the theoretical mass:

Finally, you can calculate the percent deviation or error:

a small container that holds a source of energy a solar cell that captures light energy and converts it into electricity a voltaic cell that uses the oxidation of a fuel to produce electricity

explanation:

there is none because earth is stationary and flat.
