Answer:
The volume of the gas will not change because the metal can is limiting it
Explanation:
Insead, Gay-Lussac's law tells us that the pressure will increase with the temprature unil the can eventually explodes, then allowing the volume to rapidly increase.

Find one mole
8 C = 8 * 12 = 96
9 H = 1 * 9 = 9
4 O = 4 *16 = 64
Total = 169 
1 mol = 169 grams.
0.432 mol = x
1/0.432 = 169/x
x = 0.432 * 169
x = 73.0 grams
        
                    
             
        
        
        
What amount of heat absorbs 50 g of steel (ce = 0.115 cal / g. ° C) that
does its temperature vary by 25 ° C?
Answer:
 143.75cal
Explanation:
Given parameters: 
Mass of steel  = 50g 
Specific heat capacity of the steel  = 0.115cal/g°C
Temperature  = 25°C
Unknown: 
Amount of heat = ? 
Solution: 
The amount of heat to cause this temperature change is dependent on mass and specific heat capacity of the substance. 
   Amount of heat  = m C (ΔT)
m is the mass 
c is the specific heat capacity 
ΔT is the temperature change
  Now insert the parameters and solve; 
   Amount of heat  = 50 x 0.115 x 25 
   Amount of heat  = 143.75cal
