NOTE question is incorrect: The question should be:
<span>How many moles of KCLO4 can be produced with 3.45 moles of KCl. Assume all other reactants are in excess.
.......................................................................................................................
The reaction involving formation of KClO4 is
NaClO4 + KCl </span>→ KClO4 + NaCl
From above reaction, it can be seen that 1 mole of NaClO4 reacts with 1 mole of KCl to generate 1 mole of KClO4
Thus, if all other reactant are in excess, 3.45 moles of KCl will react with 3.45 moles of NaClO4 to form 3.45 moles of KClO4.
Answer : The molar mass of unknown compound is 152.38 g/mole
Explanation :
Depression in freezing point = 
Mass of unknown compound = 16.5 g
Mass of water = 106.0 g
Formula used :
where,
= depression in freezing point
i = Van't Hoff factor = 1 (for non-electrolyte)
= freezing point constant for water = 
m = molality
Now put all the given values in this formula, we get
Therefore, the molar mass of unknown compound is 152.38 g/mole
Answer:
To the moon.
Explanation:
The farthest human space travel was 400,171 kilometers away from the Earth which was on the Apollo 13 mission to the moon. Of course though, robots and other technological devices have advanced even further into space.
