Answer:
Explanation:
The molecular formula of the monohydrate formed = 
The molecular mass of the monohydrate formed = 
So, Mass = 24 + 14 + 6 × 1 + 5 × 16 = 155 g
Mass of phosphorus = 31 g
Thus,
Answer:

The required empirical formula of the silicon oxide is SiO2.
Answer:
The volume of a 0.200 M KCl solution containing 5.00 10-2 mol of solute is 0,25 L
Explanation:
Molarity (M) means: moles of solute which are contained in 1 L of solution.
In this case we have 0,2 moles which are in 1 L, so, as we have 5x10*-2 moles we have to apply a rule of three to find out the volume.
0,2 moles ........... 1 L
5x10*-2 moles ........... x
x= (5x10*-2 moles . 1 L) / 0,2 moles = 0.25L
(we can also say 250 mL)
