The volume of the Cl₂ gas is 4.15 L.
Explanation:
This problem can be easily solved using the ideal gas law.
As in ideal gas law, it is stated that the product of pressure and volume is equal to the product of number of moles with temperature with gas constant.
PV=nRT
So, in the present case, pressure P is given as 177 kPa, temperature T = 348 K and the mass of chlorine gas is given as 18 g.
So first step, we have to determine the value of 'n' using the mass of Chlorine gas given. The mass should be converted to moles by dividing the mass with molar mass of the gas.
![n = \frac{Mass}{Molar mass}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7BMass%7D%7BMolar%20mass%7D)
As molar mass of Cl is 35.453 g/mol, then ![Molar mass of Cl_{2} = 2 * 35.453 = 70.906 g/mol](https://tex.z-dn.net/?f=Molar%20mass%20of%20Cl_%7B2%7D%20%3D%202%20%2A%2035.453%20%3D%2070.906%20g%2Fmol)
So, ![n = \frac{18 g}{70.906 g/mol} =0.254 moles](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B18%20g%7D%7B70.906%20g%2Fmol%7D%20%3D0.254%20moles)
Then, the volume can be determined with R = 8.3144×10³ L Pa K⁻¹ mol⁻¹ as shown below:
![V = \frac{nRT}{P} =\frac{0.254*8.3144*10^{3} *348}{177*10^{3} } =4.15 L](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7BnRT%7D%7BP%7D%20%3D%5Cfrac%7B0.254%2A8.3144%2A10%5E%7B3%7D%20%2A348%7D%7B177%2A10%5E%7B3%7D%20%7D%20%3D4.15%20L)
Thus, the volume of the Cl₂ gas is 4.15 L.
Answer:
2.408x10^24 molecules
Explanation:
1mole of a substance contains 6.02x10^23 molecules.
This means that 1mole of C3H8 contains 6.02x10^23 molecules.
Therefore, 4moles of C3H8 will contain = 4 x 6.02x10^23 = 2.408x10^24 molecules

<h3>
Answer:</h3>
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
<h3>
Explanation:</h3>
- The equation for the reaction shown represents the combustion of ethane.
C₂H₆ + O₂ → CO₂ + H₂O
- To balance the equation we put the coefficients, 2, 7, 4, and 6 on the reactants and products.
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
- Balancing chemical equations makes the number of atoms of each element equal on both side of the equation.
- It ensures that chemical equations obey the law of conservation of mass in chemical reactions.
