Answer:
76 mmHg is the partial pressure of oxygen on this new planet.
Explanation:
Atmospheric pressure on air on earth = 760 mmHg
On an unknown planet :
Oxygen makes up 10% of the atmosphere.
The mole fraction of oxygen gas can be written as = 
Carbon dioxide makes up 15% of the atmosphere.
The mole fraction of carbon dioxide gas can be written as = 
Nitrogen makes up the remaining 75% of the atmosphere.
The mole fraction of nitrogen gas can be written as = 
Atmospheric pressure of air on unknown planet,p= 760 mmHg (given)
Partial pressure of gases can be calculated by the help o Dalton's law of partial pressure:
Partial pressure of oxygen gas :


Partial pressure of carbon dioxide gas :


Partial pressure of nitrogen gas :


Off springs are created

3.8mL of 0.42 phosphoric acid is required.
Reaction
2H3PO4 + 3CaCL3 → Ca3(PO)4 + 6HCl
moles CaCl2 =0.16 mol/L x0.010 L = 0.0016 mol
moles of H3Po4
= 0.0016mol of CaCl2 x 2 mole of H3PO4/3mole of CaCl2
= 0.00106 mol
V of H3PO4 = 0.0016/0.42 = 0.0038L = 3.8mL
V of H3PO4=3.8mL
