How many molecules of water will be present in half mole of water?
6.022 * 10^23 = 1 mole 3.011 * 10^23 = 1/2 a mole
How many molecules of water does a 50g sample of H2O have?
A 50g sample of H2O contains approximately 2.78 x 10^24 molecules of water. This is calculated by first converting the mass to moles, then using Avogadro's number to determine the number of molecules present in that many moles of water.
How many atoms and molecules are present in 64 grams of sulphur?
12.044*10^23 atoms 1.5055*10^23 S8 molecules
How many molecules in a cup of water?
A typical cup of water, which is about 240 milliliters, contains approximately 10^24 molecules of water. This estimate is based the fact that one mole of water (about 18 grams) contains Avogadro's number of molecules (approximately 6.022 x 10^23). Since 240 milliliters of water weighs about 240 grams, it contains roughly 13.3 moles of water, leading to the vast number of molecules present.
How many atom are present in this formula 5H2?
Five molecules of hydrogen have 10 atoms.
How many hydrogen molecules and oxygen molecules would you need to start with to make 10 water molecules?
20 hydrogen 10 oxygen
How many water molecules would be released in a reaction when 10 glucose molecules are linked together?
Amylase is a catalyst (enzime).Amylose is the polysaccharide.
How many molecules of water are present in half mole of water?
In half a mole of water, there are approximately 3.01 x 10²³ molecules. This is calculated using Avogadro's number, which states that one mole of any substance contains about 6.02 x 10²³ entities. Therefore, half a mole would contain half of that number.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
Each water molecule contains two hydrogen atoms. Therefore, the number of water molecules present in the sample can be calculated by dividing the number of hydrogen atoms by 2. In this case, 3.6 moles of hydrogen atoms corresponds to 1.8 moles of water molecules. This is equal to approximately 1.08 x 10^24 water molecules.
How many molecules in 1 g of water?
3.345*10^23
How many H2O molecules are in the ocean?
There are approximately 1.332×10^24 water molecules in the ocean.
How many molecules are present in 17.0 moll of water?
To find this out you simply times 17 by avogadros number 17mol H2O X 6.022x10^23 molecules of anything/mol of anything mols cancel and you are left in molecules of H2O the answer is 1.024x10^25 molecules H2O
