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 is the empirical formula of a compound that contains 32.39 percent sodium 22.53 percent sulfur and 45.07 percent oxygen?
First assume you have 100 g of the substance & then convert to moles using the molecular weight of each element:Na: 32.39 g / (22.99 g/mol) = 1.409 mol NaS : 22.53 g / (32.07 g/mol) = 0.703 mol SO : 45.07 g / (16.00 g/mol) = 2.817 mol ONext divide each mole amount by the smallest one of the group, in this case sulfur. This gives you the ratio of each element in the compound.Na: 1.409 mol / 0.703 mol = 2.00S : 0.703 mol/0.703 mol = 1.00O: 2.817 mol/0.703 mol = 4.01Round to the nearest whole number & you get the formula: Na2SO4 (sodium sulfate)
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

How do you find the number moles of uranium are there in 3 cubic centimeters of uranium and how many are there?
To find the number of moles of uranium in 3 cubic centimeters, you would need to know the density of uranium. Once you know the density, you can calculate the mass of 3 cubic centimeters of uranium and then use the molar mass of uranium to convert the mass to moles. The number of moles can be calculated using the formula: moles = mass (g) / molar mass (g/mol).
How do you convert from moles to atoms with a single element?
Chemistry
How do you convert an element to moles?
To convert an element to moles, you need to use the molar mass of the element, which is the mass of one mole of that element in grams. You can find the molar mass of an element on the periodic table. Once you have the mass of the element, you divide it by the molar mass to find the number of moles.
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 find mass of a solute when cubic centimeters and molarity is given?
To find the mass of the solute, you first need to calculate the volume of the solution using the given cubic centimeters. Then, use the formula: mass = volume (in liters) x molarity x molar mass of the solute. Convert cubic centimeters to liters before calculating.
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 convert moles to moles per cubic dm?
To convert moles to moles per cubic decimeter (dm^-3), you need to know the volume of the substance. Divide the number of moles by the volume in cubic decimeters to get the concentration in moles per cubic dm. Mathematically, it is expressed as concentration (mol/dm^-3) = number of moles / volume (dm^3).
How is the number of moles of an element determined froma known mass?
To determine the number of moles of an element from a known mass, you use the element's molar mass (grams per mole). Simply divide the given mass of the element by its molar mass to calculate the number of moles. This relationship is described by the formula: moles = mass (g) / molar mass (g/mol).
How would we know how many moles are in a certain element?
number of moles = mass of the element/molar mass of the element
