Mass [g] (Ag)=(10.46g Ag/1cm Ag)(12.99cm Ag/1)
The "centimeters" units cancel out to leave you with grams of Ag. Just multiply across: 12.99x10.46 for your answer, in grams.

How do you calculate the weight of snow on a pitched roof?
Surface area of the roof times depth of snow gives volume of snow. Take a sample of snow and weight it to determine density (since the density of snow can vary quite a bit). Density times volume equals weight.
What is the mass of a sample divided by its volume?
Its density. Density is mass per unit volume.
Density can be determined using the formula?
I have no clue. Sorry. :( ^^ Ignore that ^^ I think Density = mass/volume.
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
Why density is the criteria for purity with respect to chemistry?
Mass and volume are extensive properties, which are dependent upon the size of the sample. A larger sample will have a greater mass and volume than a smaller sample. Density is an intensive property, which does not depend on the size of the sample. Density is a ratio of mass to volume, which does not vary with the size of the sample. The density of a larger sample will be the same as the density of a smaller sample.
How do you calculate density using a formula?
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
How do you calculate volume when you have mass and density?
Volume of a sample = (its mass) divided by (its density)
To calculate the amount of heat absorbed as a substance melts what information is not needed?
the density of the sample.

Calculate the density of a sample of gas with a mass of 30g and a volume of 7500cm3?
density= mass/volume 30g/7500cm3=.004g/cm3
What two things must you know about density?
In order to calculate the density of a substance, you must know the volume and the weight of a sample. Then the density is calculated as Density = (Weight) divided by (Volume).
How would you determine the density of a powdered dry sample which soluble in water?
1. Apparent density: - weight a graduated cyllinder - put the sample in the graduated cyllinder up to a given volume (note this volume) - weight the graduated cyllinder with the sample - calculate the mass of the powder by difference - the density is the ratio mass of the sample/volume of the sample 2. True density of a powder: you need a helium pycnometer.
Calculate the density of a sample of gas with a mass of 30 g and a volume of 7500 cm3?
.004g/cm^3
What is the mass of a sample divided by its volume?
Its density. Density is mass per unit volume.
What procedures would you do if you wanted to calculate the density of an unknown substance?
This depends on the nature and form of the sample:- for a solid with a regulate shape weight the sample and calculate the volume from the dimensions; density is the ratio between mass and volume. You can measure the volume of great sample by water displacement.- for other solids use a pycnometer- for liquids use a densimeter (simple or electronic)etc.
What is the volume of graphite?
The volume of graphite is dependent on its mass and density. You can calculate it only if you know the sample's mass and density. The same goes for any other substance or object.
