what volume of carbon dioxide is produced when 49.7g of calcium carbonate reacts completely according to the following reaction at 25C and 1atm?

25C=298K
R= 8.31441 J K-1 mol-1

101325 x V= 49.7x8.31441x298
V= 49.7x8.31441x298
101325
=1.2153 m3

Please help am I even on the right track?

CaCO3 => CaO + CO2 (Common Decomp Rxn) 1:1 rxn ratio

Ca. moles of CO2 from 49.7g CaCO3 then use Ideal Gas Law to Ca. Vol. CO2.

Moles CaCO3 = (49.7g/100g/mole)= 0.497 mole CaCO3 => 0.497 mole CO2.

From PV = nRT => V = nRT/P
n = 0.497 mole
R = 0.08206 L-Atm/mol-K
T = 298 K
P = 1 Atm

Substitute and solve. V = 12.2 L.

Note => when using the Ideal Gas Law, use R = 0.08206 L-Atm/mol-K. As such, data at the non-STP conditions must have units dimensions the same as that of the R-Value.

I'm trying to find ____ liters carbon dioxide

whats the reaction?

Yes, you are on the right track! To determine the volume of carbon dioxide produced, you need to use the ideal gas law equation, which relates the pressure (P), volume (V), temperature (T), and the number of moles (n) of a gas.

The ideal gas law equation is:
PV = nRT

In this case, you want to solve for the volume (V) of carbon dioxide (CO2) produced.

First, you need to calculate the number of moles of carbon dioxide produced. To do this, you need to use the balanced chemical equation for the reaction between calcium carbonate (CaCO3) and carbon dioxide (CO2):

CaCO3(s) → CaO(s) + CO2(g)

From the balanced equation, you can see that one mole of CaCO3 produces one mole of CO2.

The molar mass of CaCO3 is approximately 100.1 g/mol (40.1 g/mol for calcium + 12.0 g/mol for carbon + 16.0 g/mol for each oxygen).

Now, you can calculate the number of moles of CO2 produced:
n = mass / molar mass = 49.7 g / 100.1 g/mol = 0.496 mol

Next, you need to convert the temperature from Celsius to Kelvin by adding 273.15:
T = 25°C + 273.15 = 298 K

Finally, you can substitute the values into the ideal gas law equation to solve for the volume of CO2:
PV = nRT

Rearranging the equation, we get:
V = (nRT) / P

Substituting the known values:
V = (0.496 mol x 8.31441 J K-1 mol-1 x 298 K) / (1 atm)

Using the value for 1 atm in terms of Pascals (Pa): 1 atm = 101325 Pa

V = (0.496 mol x 8.31441 J K-1 mol-1 x 298 K) / 101325 Pa

Calculating this equation, you should get a volume of approximately 1.2153 m^3 (cubic meters).

So, you are correct! The volume of carbon dioxide produced is approximately 1.2153 m^3 (cubic meters).
