Answer : The total mass of carbon dioxide and water produced will be, 65.7 grams.
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,

According to the law of conservation of mass,
Total mass of reactant side = Total mass of product side
Total mass of
= Total mass of 
As we are given :
Total mass of
= 65.7 grams
So,
65.7 grams = Total mass of 
Therefore, the total mass of carbon dioxide and water produced will be, 65.7 grams.
75.0 degrees Celsius = 75.0 + 273 = 348 K.
Assuming pressure is held constant,

D. the student's conclusion shows experimental bias
I...what? What are you saying my boi
Based on the scenario, the matter escaping from the pot is an example of an : C. Open system because heat and matter are both able to enter or leave the system
The key word here is 'steam can be seen escaping from the pot' , which indicate that the matter and heat able to leave the system after it's entered.
hope this helps
