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.
42.1g/ 59g/mol (grams/molar mass of C3H8O)
n-propanol is C3H8OAdd up atomic massesand so you'll get the molecular weight (rather: use molar mass) = 60.06 g/mol3*12.00 for 3 Carbon atoms = 36.008*1.008 for 8 Hydrogen atoms= 8.0641*15.99 for one Oxygen atom= 15.999
Oxygen atoms weigh more than Hydrogen atoms.
19.37 g/mol
Propanol can be burned.
The percent by mass of oxygen in N2O4 is 69,56 %.
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 mass percent of oxygen in SO2 is 50 %.
The more percentage of water is present in the lower percentage of propanol thus making it more polar.
To determine the percentage of oxygen in FeCr2O4, you would first calculate the molar mass of the compound (iron(II) chromite) using the atomic masses of each element (Fe = 55.85 g/mol, Cr = 51.996 g/mol, O = 16 g/mol). Then, calculate the molar mass percentages of each element within the compound, and finally, determine the percentage of oxygen by mass in the compound.
Estriol (C18H24O3) contain 16,644 % oxygen.
60%
The mass of the elements that are not oxygen equals 194.8g. The mass of oxygen is 230g - 194.8g = 35.2g of oxygen. Mass percent of oxygen = 35.2g O/230g x 100 = 15% O
