Answer:
Explanation:
1. Calculate the moles of CoCl₂
2. Calculate the volume of solution
We would need 0.037 mol. We know that because of a formula we can use and some data from the problem. The formula would be:
n= Number of heat in kj x 2 moles
--------------------------------------
5460 kJ
The number of Kj of heat is provided(100 kJ). The standard enthalpy of combustion is -5460.0 kj. so we multiply 100 kj and 2 moles and then we divide on 5460 kj and the answer is 0.037 moles.
<span>The number of molecules of each gas must be equal since 1 mol of any gas needs to contain 6.02x10^23 molecules. So 1mol O</span>₂ and 1mol CO both need to contain 6.02x10^23 molecules
