Answer:
0.7 g/cm³

< The formula for density is 
where m = mass, v = volume, and p = density. An easy way to remember the formula is density equals love. I found this easy to remember because p = ♡ and when you think about it, if you split the heart in half through the middle like a fraction, it will make 
(if you don't understand what I'm saying, try writing it out and you will be able to see what I'm talking about!)
We already know that the block is 253 g so the mass is 253 g.
To find the volume, always multiply the 3 values width, length, and height whenever you are trying to find the volume of a block.
15.24 cm x 6.64 cm x 3.56 cm = 360.25 cm³
Now plug it into the formula.

Answer:
ΔS = -661.0J/mol is the entropy change for the system
ΔS = -842J/mol.K is the entropy change for the surroundings
Explanation:
From the relationship between ΔG, T, ΔH and ΔS,
Mathematically, ΔG = ΔH - TΔS
TΔS = ΔH - ΔS
ΔS = ΔH - ΔS / T
but ΔG = -54 kJ/mol, ΔH = -251 kJ/mol and T = 25 °C (298 K)
plugging into the equation,
ΔS = -251 kJ/mol - ( -54 kJ/mol) / 298
ΔS = -0.6610KJ/mol or in J.mol
ΔS = -661.0J/mol is the entropy change for the system
- For entropy change for the surroundings = ΔS = ΔH/T
- ΔS = -0.84KJ/mol.K or -842J/mol.K is the entropy change for the surroundings
Fire transfers heat by CONVECTION, meaning some heat rises, and FALL, meaning some heat goes out in every directions.
