Answer:
a) The molecular mass of each compound dinitrogen pentaoxide is 108 g/mol.
b) The molecular mass of each compound lead(ll) nitrat is 331 g/mol.
c) The molecular mass of each compound calcium peroxide is 72 g/mol.
Explanation:
a) Molecular mass of dinitrogen pentaoxide that be M.
Mass of nitrogen atom = 14 g/mol
Mass of oxygen atom = 16 g/mol
b) Molecular mass of lead(ll) nitrate that be M.
Mass of lead = 207 g/mol
Mass of nitrogen atom = 14 g/mol
Mass of oxygen atom = 16 g/mol
c)Molecular mass of calcium peroxide that be M.
Mass of calcium atom = 40 g/mol
Mass of oxygen atom = 16 g/mol
Answer:
713mmHg
Explanation:
By using Dalton's law of partial pressure, the pressure outside the gas container is equal to the pressure inside it and this pressure equals the sum of the pressures of water and the gas.
i.e, P(total) = P(gas) + P(water)
P(gas) = P(total) - P(water)
P(gas) = 735 - 22
P(gas) = 713mmHg
