Is KCl a solid or gas in this graph?
You need to determine the saturation point before you can decide the type of solution.
(Sat. pt. From graph)x(%H2O)
52 g x 2.5 = 130 g
Saturation point in 250g of water
186g NH4Cl (62g x 3)
110g x 1.25= 137.5
The same as what it asks
Hint: what is the equation for density?
Divide by molar mass foo!
Molar mass of NaOH (40.00 g/mol)
We want Liters, leave this alone
6.00 mol NaOH or 1 L solution
1 L solution 6.00 mol NaOH
There’s 1000mL in 1L!! Remember this foo!
V1= ? V2= 100mL
