What is the percentage mass of oxygen in cocaine?
Cocaine is C17H21NO4 and has a molar mass of 303.353 g/mole. Mass of oxygen in cocaine is 4x16 = 64. So, % oxygen by mass is 64/303.353 (x100) = 21% (to 2 sig. figs)
What is the percentage mass of oxygen in morphine?
16.8%
What is the percentage mass of oxygen in MgSO4?
gh
Percentage of oxygen in human body?
65% by mass
How does combining hydrogen and oxygen to create water relate to the law of conservation of mass?
The mass of the oxygen and hydrogen that react to form water will be exactly equal to the mass of the water produced.
Percentage by mass of components of water?
11% Hydrogen and 89% Oxygen
What is the percentage composition of oxygen in C7H15NO3?
The percentage of oxygen (in mass) is 29,776 %.
How do you calculate how many grams of water are produced from 22.1 grams of oxygen?
First find the percentage by mass of oxygen in water. The formula for water is H2O, showing that water contains two hydrogen atoms for every atom of oxygen. The gram atomic masses of hydrogen and oxygen are 1.00794 and 15.9994 respectively. Therefore, the percentage of oxygen in water is 100{15.9994/[15.9994 + 2(1.00794)]} or about 88.8 %, to the justified number of significant digits; the ratio of the maximum mass of water that can be made from a given mass of oxygen is 1/0.888 or about 1.126; and the answer to the question is this number multiplied by the stated mass of oxygen, or 24.9 grams, to the justified number of significant digits.

What is the percentage mass of oxygen in coedine?
Codeine : C18H21NO3Molecular Mass: 299Mass of oxygen present: 3 X 16 = 48Mass% of Oxygen : 48/299 * 100 = 16 %
How percentage of oxygen is more in water than hydrogen?
This is true for mass-%. Oxygen is 16 times heavier than hydrogen, that outfigures the double elemental ratio for hydrogen to oxygen (2:1) by factor 8 times.
What is the percentage composition for CO?
The molecular mass of CO is 28. The carbon percentage by mass is ~43%. Hence the oxygen percentage by mass is ~57%.
