PLEASE HELP ASAP Why can ionic table salt and covalent rubbing alcohol both dissolve in water?

Alcohol's polar bonds and salt's ions have higher potential energy than the potential energy of the hydrogen bonding between water molecules.

Alcohol's polar bonds and salt's ions are both able to form strong attractions to the polar water molecules.

The temperature of liquid water is high enough to allow anything to mix well with its fast-moving molecules.

The air pressure above the water is greater than the pressure exerted by the moving water molecules.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
