Answer:
Based on Boyle's law, which of the following statements is true for an ideal gas at a constant temperature and mole amount?
A) Pressure is directly proportional to volume.
B) Pressure is inversely proportional to volume. CORRECT ANSWER!!!
C) The number of collisions is independent of pressure.
D) The number of collisions decreases with increase in pressure.
B is the CORRECT answer!!!
Balanced chemical equation is
3CaCl2 +2Na3PO4-->6NaCl +Ca3(PO4)2
moles of CaCl2 =89.3g/[ (35.5x2) +40]=0.805moles
from the equation above the ratio of CaCl2 to Ca3(PO4)2 is 3:1 therefore the moles of Ca3(PO4)2 is 0.809/3=0.268moles
mass is therefore 0.268 x310.18(R.F.M of Ca3(PO4)2 ) =83.23grams
