What make up 10 to 30 percent of the cell mass?
oxygen
What are the steps on finding what the mass of oxygen in a 10 g of zircon?
Well, the formula for zircon is ZrSiO4 so, this means that you need to find the molar mass of the entire thing. Once you have this you find the percent mass that oxygen takes, by dividing the mass of the oxygen by the mass of the total compound. Then you multiply this number by the 10g and voila.
A compound is formed when 48 grams of carbon 8 grams of hydrogen and 68 grams oxygen combine what is the percent by mass of oxygen?
The percentage of oxygen is 54,84 %.
What 4 elements make up 95 percent of the earth's mass?
Iron, Oxygen, Silicon, and Magnesium
What takes up 67 percent of earths mass and consist mainly of silicon oxygen and magnesium?
mantle
What is the atomic mass of trinitrotoluene?
1433
What is the mass percent of oxygen in of N2O4?
The percent by mass of oxygen in N2O4 is 69,56 %.
How find percent compsotion of oxygen in Na2O?
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.
What is the mass percent of oxygen in SO2?
The mass percent of oxygen in SO2 is 50 %.
What is the percent of oxygen by mass in a pure sample of FeCr2O4?
the answer is 29 percent
What is the mass percent of oxygen in estriol?
Estriol (C18H24O3) contain 16,644 % oxygen.
What is the approximate percent by mass of oxygen in SO3?
60%
If 230 g sample of a compound contains 136.6 g of carbon 26.4 g of hydrogen and 31.8 g of nitrogen The rest is oxygen What is the mass percent of oxygen in the compound?
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
Why if sucrose is 51.5 percent oxygen by mass and only 6.4 percent hydrogen by mass is there twice as many hydrogen atoms than oxygen atoms?
Oxygen atoms weigh more than Hydrogen atoms.
What is the mass percent of oxygen in phenylalanine?
19.37 g/mol
Why is it inaccurate to say that CO is 50 percent oxygen?
Because the mass of carbon is not the same as that of oxygen.
What make up 10 to 30 percent of the cell mass?
oxygen
