For solids and liquids, if you know the density in grams per cubic centimeter, and the Atomic Mass (grams per mole), then you can calculate it.
Moles * (atomic mass) / (density) = volume.
For gasses: you need to know the Pressure and Temperature, and use PV = nRT, so V = n*R*T/P, then convert to cubic centimeters. Or if at Standard Temperature and Pressure (0°C and 1 atmosphere), an Ideal Gas has a volume of 22.4 liters/mole (22400 cm3 / mole)

How do you convert cubic cm to moles?
You cannot convert cm3 to moles. They do not measure the same quantity. Cubic centimeters measure volume (the amount of space an object takes up) and moles measure the amount of a substance. The mole is one of the seven fundamental SI units, whereas cubic centimeters is a derived unit.
In the reaction 2 RbNO3-- 2 RbN plus 3O2 how many moles of O2 are produced when 5 mol of RbNO3 decompose?
5 moles RbNO3 (3 moles O2/2 moles RbNO3) = 7.5 moles oxygen gas produced
What can the coefficients in a balanced chemical equation always express the ratio of?
Moles of one substance compared to moles of the second substance. Ex. moles of reactant A compared to moles pf product F
What of mass of 10.0 ml water if mass of beaker plus 10.0 ml of water equals 53.961 g and mass of beaker is 43.899 g?
use molarity M=mol/l u have to convert grams to moles u need to know what the substance is
What does the 2 in 2NH3 mean?
The coefficient (in this case a 2) indicates the number of moles or molecules of the compound. So, 2NH3 means there are 2 moles or 2 molecules of ammonia (NH3).

How do you convert from moles to atoms with a single element?
Chemistry
How many moles of uranium are there in 3 cubic centimeters of uranium?
o,24 mol
How do you convert moles to milligrams of an element?
First off you multiply moles by 1000 to convert to millimoles. Next you multiply by the molecular weight (found as the bigger figure on the element on the periodic table).
How is the number of moles of an element determine from a known mass?
The mass of 1 mole of the element is used as a conversion factor to convert grams to moles
How do you convert an element to moles?
to convert an element to moles you need to setup and equation, for our example we will be using 5g of O2 or oxygen. You need to know what O2's molar mass is as well, it is 32g. So the equation would be 5g of O2 / 32 = .16 moles of O2. So to convert moles to grams all you do is multiply the moles given by the molar mass of the element/compound and you have your grams Hoped this helped : )
How many moles does 8 cubic centimeters of oxygen at room temperature and pressure contain?
The answer is 7,145.10-4 mol.
How do you find the number moles of uranium are there in 3 cubic centimeters of uranium and how many are there?
Approx. o,24 mol.
How is the number of moles of an element determined froma known mass?
the molar mass is used as a conversion factor to convert grams to moles
How many moles of nitrogen and oxygen are in a cubic foot?
Molecules or moles? And in a cubic foot of what? Air?
How do you convert moles to moles per cubic dm?
You need to know the molar volume, which is essentially the density. Usually, the density is reported in grams per cm3 (or per mL, which is equal to 1 cm3). First convert the moles into grams (see the Related Questions link to the left for how to do that), and then divide by the density to get the number of cm3 that many moles occupies. Then convert cm3 to dm3 (1 cm3 = 0.001 dm3 or 1 dm3 = 1000 cm3).
What is the mole ratio that can convert from moles of a to moles of b?
a moles (b moles/a moles) = b moles
