The pond weeds are the producers because they are a plant
There are actually three: One oxygen atom and two hydrogen atoms.
It should be equal to the mass of the carbon plus the mass of the oxygen. This is because of the conservation of mass law. Mass is never created or destroyed only conserved. Hope this helped
We calculate first for the number of moles of gases in the sample through the ideal gas equation.
n = PV/RT
n = (725 mmHg/760 mmHg/atm)(0.255 L) / (0.0821 L.atm/mol.K)(65 + 273.15)
n = 8.76 x 10^-3 mol
Then, we calculate for the mol N2 using the ratio of the pressure.
n N2 = (8.76 x 10^-3 mols)(231 mmHg/725 mmHg)
n N2 = 2.79 x 10^-3 moles
Then, multiply the value with the molar mass of N2 which is 28 grams per mol giving us the answer of 0.078 grams.
