Answer: endothermic
Explanation:
The cake (the subject) is receiving heat from the oven (its surroundings) in order to bake.
97.2g H20 x 1mole/18g of H2O x 6.022x10^23 molecules/1mole= 3.25 x10^24 molecules of H2O

Answer:
10.69g/cm^3 or 0.0106kg/m^3
Explanation:
10.69 g/cm^3: I wrote this answer because your question doesn't mention whether volume is in cm^3 or m^3. If its in cm^3, then this is your answer.
0.0106kg/m^3: This might also be the answer if the volume is in m^3. If it is in m^3 then you have convert grams into kilograms.
So technically since you questions incomplete, the equation for measuring density is P= m/v
P= rho (density)
m= mass
v= volume
