A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
3.6 moles hydrogen atoms (1 mole water/2 mole H)(6.022 X 1023/1 mole water molecules) = 1.1 X 1024 molecules of water =======================
How many grams of hydrogen are in one mole of water?
One mole of any substance contains 6.022x10 to the power of 23 molecules of that substance. A water molecule contains two hydrogen atoms so one molecule of water has 12.044x10 to 23 hydrogen atoms.
How many H-atoms are present in 5 molecules of propane?
Five molecules of propane have 40 hydrogen atoms.
How many hydrogen atoms are in 6 molecules of HOCH2Ch2OH?
12
How many hydrogen atoms are in a molecules of table sugar?
22
How many molecules of hydrogen in water?
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
How many molecules are present in a molecule of hydrogen?
there are 2 atoms of hydrogen in water
How many hydrogen atoms are needed to form five water molecules?
Chemical formula for water is H2O. One water molecule has 2 hydrogen atoms. That means 10 hydrogen atoms are needed to form five water molecules.The ration between hydrogen and oxygen in a water molecule is 2:1. In five water molecules, there are five oxygen atoms. According the ratio, there are 10 hydrogen atoms.
How many oxygen atoms are in water molecules?
3 oxygen atoms in three molecules of water.- There are 3 total atoms in water, which is H2O. There are 2 hydrogen atoms (H), and 1 oxygen atom (O).
How many oxygen atoms are in molecules of water?
3 oxygen atoms in three molecules of water.- There are 3 total atoms in water, which is H2O. There are 2 hydrogen atoms (H), and 1 oxygen atom (O).
How many atoms are in five molecules of hydrogen?
ten as each hydrogen molecules contains two atoms.
How many oxygen atoms are in 6 molecules of water?
6 atoms of oxygen are present. Three O2 contains 6 O atoms.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
3.6 moles hydrogen atoms (1 mole water/2 mole H)(6.022 X 1023/1 mole water molecules) = 1.1 X 1024 molecules of water =======================
How many molecules contains 0.5L of c2h6o and how many hydrogen atoms?
The answer is 51,568.10 ex.23 molecules and 309,408.10 ex. 23 hydrogen atoms.
How many atoms of hydrogen are there in the mole of H2O molecules?
There are 2 hydrogen atoms and 1 oxygen.
How many atoms of hydrogen are in two molecules of benzene?
Two atoms.
How many atoms are needed to make 30000000000000000000 molecules of water?
There are 3 atoms in one molecule of water (H2O is two hydrogen atoms and one oxygen atom)... so just multiply the number of molecules by 3.
