One marble typically weighs around 5 grams. The molecular mass of a water molecule is approximately 18 grams/mol. This means that 1 marble has the mass of roughly 5/18 = 0.28 moles of water molecules. To find the number of molecules, you would multiply this quantity by Avogadro's number (6.02 x 10^23), resulting in approximately 1.7 x 10^23 water molecules having the mass of 1 marble.

When a marble is dropped in a bucket of water it sinks to the bottom. Is it because the marble weighs more than an equivalent volume of the water or the marble has greater mass volume than the water O?

All of the above? You can say the same thing in many ways. All of the following are different ways of saying the same thing, and all are correct: The marble sinks because the marble weighs more that an equivalent volume of water. The marble sinks because its density is greater than the density of water. The marble sinks because it has a greater mass than than same volume of water (and there is gravity/acceleration).


Does marble absorb water?

Yes. Raw marble (untreated marble) will absorb water. However this doesn't mean it will absorb so much water it will have a significantly larger mass. Treated marble that has a thin silicon layer will not absorb water.

What has more mass the catapult or the marble?

The catapult has more mass than the marble, as it is a larger object designed to launch the marble. The marble is smaller and has less mass than the catapult.


Does ice molecules has less mass than water molecules?

How did the mass of the target marble compare with the mass of the shooter marble in these collisions?

In elastic collisions, the mass of the target marble is equal to the mass of the shooter marble since momentum is conserved, so the target and shooter will have the same mass. In inelastic collisions, the mass of the target marble may be greater or lesser than the mass of the shooter marble depending on the degree of energy loss during the collision.


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.


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.


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.

How many moles of water molecules H2O are present in a 27 gram sample of water?

There are 1.5 moles of water molecules in a 27 gram sample of water. This is calculated by dividing the mass of the sample (27 grams) by the molar mass of water (18 grams/mol).
