Why water have measurable mass?
Water has measurable mass because it is composed of molecules, which are made up of atoms. These atoms have mass, and when they come together to form a water molecule, that mass adds up. The total mass of water is a measure of the sum of all the masses of its individual molecules.
What is the mass of 500 trillion molecules of water?
500 trillion = 500x10^12 molecules = 5x10^14 molecules5x10^14 molecules x 1 mole/6.02x10^23 molecules x 18 gram/mole = 15x 10^-9 grams = 1.5x10^-8 gThis is obviously a very small amount of water.
How many moles of water molecules h2o are present in a 27 rams sample of water?
To find the number of moles of water molecules in a 27 gram sample, you need to divide the mass by the molar mass of water (18.015 g/mol). 27 g / 18.015 g/mol = approximately 1.5 moles of water molecules.
How many grams are in 4 molecules of water?
The molar mass of water (H2O) is approximately 18 grams/mol. Therefore, for 4 molecules of water, the total mass would be 4 x 18 = 72 grams.
What is the percentage of water to the nearest tenth in this compound BaOH2 8H2O?
The compound Ba(OH)2·8H2O has 8 water molecules associated with it. To find the percentage of water in the compound, calculate the molar mass of the water molecules (8H2O) and the molar mass of the entire compound (Ba(OH)2·8H2O). Then divide the molar mass of the water by the molar mass of the entire compound and multiply by 100 to get the percentage of water.
Does ice molecules has less mass than water molecules?
no it has more
Why water have measurable mass?

Does water have mass?
Yes, water has mass. All matter, of which water is one kind, has mass.
Does changing the mass of water change the mass of one cubic centimeter of water?
You can change the mass of water in two ways: increase or decrease the amount of water or change the isotopic composition of the molecules of water. The first will have no effect on the mass of 1 cc of water. The second will. If you replace the hydrogen atoms in the "normal" water molecules with deuterium atoms you will increase the density (mass/cc) of the water.
Does water vapour have mass?
Yes, water vapor does have mass. Water vapor is a gas composed of water molecules, and like all matter, it has mass. However, the mass of water vapor is much lighter compared to liquid water.
Why does the volume of the water vapor increase and the mass remain constant When 1 gram of water is evaporated?
Mass is mass. It is constant. Changing water from liquid to gas does not change the mass, it only changes the density, which is mass per volume. Look at it another way - in gaseous form, the same mass of water has the same number of molecules of water - but those molecules are simply further apart.
What is the mass of 500 trillion molecules of water?
500 trillion = 500x10^12 molecules = 5x10^14 molecules5x10^14 molecules x 1 mole/6.02x10^23 molecules x 18 gram/mole = 15x 10^-9 grams = 1.5x10^-8 gThis is obviously a very small amount of water.
When 1 gram of water is evaporated the volume of the water vapor increases but the mass remains constant Why does the mass of the water remain constant?
There is no way that mass can be created or destroyed. Here is an informal way to consider the situation. When you evaporate the water, the distance between the molecules increases. But no new molecules are created (or destroyed). Well, the mass is not simply the total number of molecules - but this gives you an idea how this situation works.
When boiling water turns to steam what stays the same?
The mass of the water The number of molecules
When water evaporates does its mass decrease?
Yes, when water evaporates, its mass does not decrease. The water molecules simply change from a liquid state to a gaseous state, but the total mass of the water remains the same.
What is the atomic mass of 5 water molecules?
The atomic mass of a single water molecule (H₂O) is approximately 18.02 grams per mole, calculated from the atomic masses of hydrogen (about 1.01 g/mol) and oxygen (about 16.00 g/mol). Therefore, the total mass of 5 water molecules can be calculated by multiplying the mass of one water molecule by 5, resulting in about 90.1 grams per mole for 5 molecules. However, since the atomic mass is typically expressed per mole, the mass of 5 water molecules in grams would be significantly less than this value.
Does the mass increase or decrease when anhydrous compounds decompose?
when anhydrous compounds decompose their mass will decrease
