Mass is just the quantity of matter in the marshmallow, so you just need weigh it.
If you wanted its density, then you must also determine the volume.
The simplest way would be to slice off the irregular sides of the marshmallow to make some simple shape, and thus measure the (e.g. simple cube) volume of the sample. There will be a small error, because the original edges of the sweet would be different from the remainder.
Otherwise, determine the volume by immersing the marshmallow in a non-wetting fluid, and determine the volume in the Archimedes manner.
I'm not sure what a good non-wetting liquid would be. Mercury suggests itself, but that is a dangerous fluid. Perhaps a 'seething' liquid such as Lycopodium Powder would do, or any powder with a low density. A few ounces grams of small glass beads might be worth a try?
Depends on the marshmallow and the marble... a 2g marble will have the same mass as a 2g marshmallow........
To calculate the atomic mass of an element, add up the mass of protons and nuetrons.
No. you will know the volume of the unknown mass after you calculate the mass of ca0
Marshmallows vary in density. They are not a pure substance. As they contain air bubbles their density can be altered merely by squeezing them as can their volume but their mass would be the same even if smashed into pieces. The marshmallow's physical dimensions would change.
Different manufacturer's marshmallows will be of different mass so there is no simple answer. If you want the answer you will have to do some work:Get an unopened packet of marshmallows. The net mass should be given on the packet. Suppose that is g grams. Next open the packet and count the number of marshmallows in the packet. Suppose that number is n.Then the mass of each marshmallow, on average, is g/n grams.Having done ALL that hard work, you deserve a marshmallow - or two!
The same way you calculate the atomic mass of other elements.
Calculate the mass of Oxygen in the tin oxide
To calculate the atomic mass of any element, add the no. of protons and neutrons. There sum will be the atomic mass. The mass of electrons is not counted towards the atomic mass.
Protons and neutrons= mass
Not enough information. To calculate mass, you would need volume and density (mass = volume x density).
Basically by weighing it. Although mass is not the same as weight, if you know the weight and the gravity, you can calculate the mass.Basically by weighing it.

To calculate the mass of the cell you will need to know the mass and atomic number of the element. Multiply the number of atoms by the amount of grams per mole to get the mass.
