Hi, You need to work out how many moles of water you have in 1L of water. Then you need to know that the Avrogadro constant is the number of molecules on a mole of anything. so; water = H2O Atomic weights: Hydrogen = 1 Oxygen = 16 Mole weight of water therfore; 18 grams 1L water = 1000 grams avrogadros constant is 6.0221415 x 10^23 :. 1000 /18 = 55.5555' moles water 55.5555' x Avrogadros const = 33456308210325000000000000 = 3.3456 x10 ^25 molecules of water. Please check my figures - I don't have a scientific calculator handy. Hope this helps, Mike.
2.60x10^23 water molecules contain 2.60x10^23 molecules of water.
There are 33.33 units of 30g in 1kg.
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.
A mole of water contains avagadro's number of molecules of water. Therefore 5.65 moles contains 5.65 * 6.022x1023 molecules of water which equals 3.40243x1024 molecules of water.
The polarity of water molecules is what makes water a good solvent. Water's partial positive and negative charges allow it to interact with a wide variety of molecules, making it capable of dissolving many different substances.
well the density of water at 25 oC is approximately 1kg/L. So about 1 L
1kg of pure water would take up 1000 mililitres.
Yes, 1kg of water equals 1kg of steam, as they are both forms of water in different states. The difference lies in their physical state, with water being in liquid form and steam being in gaseous form, but their mass is the same.
how many candles of 1kg wax
How much salt is in 1kg of water
1kg=9.81N
The answer is 0,166.10e23 molecules.
It is: 5kg-1kg = 4kg
There are 4 250g in 1kg. This is because 250g is one-fourth of 1kg.
2.60x10^23 water molecules contain 2.60x10^23 molecules of water.
There are 33.33 units of 30g in 1kg.
