You dissolve 4.5 mol of potassium hydroxide to make a 2 l solution. what is the molarity of the solution?

Data:
M (molarity) = ? (Mol/L)
m (mass) = ? (in grams)
V (volume) = 2 L 
MM (Molar Mass) of Potassium Hydroxide (KOH)
K = 1*39 = 39 amu
O = 1*16 = 16 amu
H = 1*1 = 1 amu
------------------------------------
MM  of KOH = 39+16+1 = 56 g/mol

***Let's find the mass
Data:
n (number of mols) = 4.5 mols
m (mass) = ? (in grams)
v (volume) = 2 L

Formula:






***Let's find the molarity:

Formula:



Solving:

Ithink this is what you meant. the temperature at which a liquid begins to boil is called the boiling point. the boiling point of water is 212°f or 100°c.  and at that point will start to turn into steam (gas)
