Phytoplankton in the Earth's oceans.
Definitely the 20% oxygen because there is less of it and the solute is always the lesser amount.
The percent of oxygen is 53,298 %.
About 21% of air is oxygen.
Percent composition means finding the total mass of each element in a molecule and then dividing it by the molecular mass. Use the molecular formula to help you find out how many atoms of each element you'll need. For carbon: 6 C x 12 g = 72 g For hydrogen: 10 H x 1 g = 10 g For oxygen: 5 O x 16 g = 80 g Molecular mass = C + H + O = 72 + 10 + 80 = 162 g Percent composition of C = 72/162 = 0.4444 = about 44.45% Percent composition of H = 10/162 = 0.061728395 = about 6.17% Percent composition of O = 80/162 = 0.49382716 = about 49.38%
To find the percent composition of oxygen in Na2O, find the total molar mass of the compound. Then, divide the molar mass of oxygen by the molar mass of the compound, and multiply by 100% to get the percent oxygen.
The Earth's grass produce 20 to 30 percent oxygen. The other 70 to 80 percent of oxygen is produced by marine plants.
no
phytoplankton :)
Nitrogen
none of them are solutes
About 70% of our oxygen is indeed produced by marine plants. The statement about the rain forests is wrong, they are now known to be essentially oxygen neutral, with little or no net oxygen production at all. That's not saying, it isn't worth saving them.
Earth's atmosphere is 20 percent oxygen and 80 percent nitrogen. In space, there is no oxygen due to the lack of gravity to help it form.
80 percent
Definitely the 20% oxygen because there is less of it and the solute is always the lesser amount.

nuclear power plnts
no 70 percent of all oxygen comes from algee and 100 percent of plants are decendant of algee
