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.
The mass is 74,7 mg.
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 size marble? And is it made of marble or glass?
To calculate the density of a marble, you need to know its volume in addition to its mass. Density is defined as mass divided by volume (Density = Mass/Volume). If the marble weighs 15 grams, you would need to measure its volume (for example, by water displacement) to find the density. Without the volume, the density cannot be determined.
To calculate the number of water molecules in 1.802 grams, first find the molar mass of water (H2O = 18.015 g/mol). Then, divide the given mass by the molar mass to get the number of moles (1.802 g / 18.015 g/mol = 0.1 mol). Finally, multiply the number of moles by Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of water molecules (0.1 mol * 6.022 x 10^23 molecules/mol = 6.022 x 10^22 molecules).
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).
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.
The mass is 74,7 mg.
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.
no it has more
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.
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.
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.
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.
The mass of a regular size marble is 1.27 grams.
I'm pretty sure a marble has less mass
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).
