To identify the amount of chloride ions present in 0.1 mol
of MgCl2, first know the amount of mols of Chloride. The answer is 0.2 mol
since you just need to multiply 0.1 to 2 because there are 2 chloride in the
compound. Then, multiply the mols to 6.02x10^23. The answer would be
1.204x10^23 chloride ions.

Explanation:
When something is burned, it means that it is <u>reacted with oxygen</u>. Steel wool is made out of iron, which bonds with oxygen atoms to form iron oxide which is solid in this reaction. Since, there are now more solid atoms in the steel wool, it will weigh more than before it was burned.

The correct sentence is this:
THE VAPOUR PRESSURE OF ACETONE IS SMALLER THAT THAT OF WATER AT THE SAME TEMPERATURE.
Acetone will evaporate more quickly that water when exposed, this is because, its vapour pressure is smaller than that of water. The vapour pressure of water is greater, thus, at the same temperature and pressure, it will take less pressure to vapourize acetone.
