The molarity is 31.0 * x / 2, such that x is the molar mass of Ca₃(PO₄)₂
Answer:
759779.6 torr
Explanation:
Initial volume, V₁ = 4001 mL
Final volume, V₂ = 3002 mL
Initial pressure, P₁ = 750.1 atm
We need to find the final pressure at a constant temperature. Let it be P₂. 
We know that,
1 atm = 760 torr
So,
999.71 atm = 759779.6 torr
Hence, there will be 759779.6 torr pressure.
Radiation or heat by the sun
