At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas. At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas.

(mol dm-3) = moles (mol) Volume (dm3) Conc. (g dm-3) = mass (g) Volume (dm3) Page 2 Calculations in Chemistry MOLES A measure of the amount of substance. Number of = mass (m) moles (n) Molar mass (Mr) Mass is measured in grams. Molar mass is calculated by adding the atomic masses (from the Periodic Table) together.

Mass percent differs from volume percent, as only mass is an additive quantity. The mass of the solution is the sum of the components. Volume, on the other hand, isn't always additive, as molecules of the solute will fit into open spaces between molecules of solvent, resulting in less volume than expected.

Molar volume at STP can be used to convert from moles to volume and from volume to moles for gaseous samples. The fact that 1 mole = 22.4 L is the basis for the conversion factor.

Compute the volume of a solution in liters, given the number of moles and molarity, by dividing the number of moles by the molarity in units of moles per liter. For example, a solution containing 6.0 moles and a having a molarity of 3.0 moles per liter has a volume of 2.0 moles per liter.

Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

9.4: The Mole-Volume Relationship: Avogadro's Law. A plot of the effect of temperature on the volume of a gas at constant pressure shows that the volume of a gas is directly proportional to the number of moles of that gas. This is stated as Avogadro's law.

Concentration is usually expressed in terms of mass per unit volume. However, the solute concentration may also be expressed in moles or units of volume. Instead of volume, concentration may be per unit mass. While usually applied to chemical solutions, concentration may be calculated for any mixture.

Density and Volume are inversely proportional to each other. Mass and volume are not the same. Thus from the above formula, we can say that, For a fixed mass, When density increases, volume decreases.

The relationship between pressure and volume is inversely proportional. (a) The graph of P vs. ... It is summarized in the statement now known as Boyle's law: The volume of a given amount of gas held at constant temperature is inversely proportional to the pressure under which it is measured.

Avagadro's Law- Gives the relationship between volume and amount of gas in moles when pressure and temperature are held constant. If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases.

So, the substance is important for an accurate conversion. For those people looking for the formula for converting volume to weight, and vice-versa, it looks like this (adapted from answers.com): Density = mass/volume (ρ=m/V). So V=m/ρ and has units (kilograms)/(kilograms per cubic meter)=cubic meter.

The answer is 1000. We assume you are converting between mole/litre and mole/milliliter. You can view more details on each measurement unit: mole/litre or mol/mL The SI derived unit for amount-of-substance concentration is the mole/cubic meter. 1 mole/cubic meter is equal to 0.001 mole/litre, or 1.0E-6 mol/mL.

Gay-Lussac's law states that pressure (P) and temperature (T) are directly proportional. Avagadro's law states that the amount (n) of a substance is directly proportional to the volume (V). The combined gas law is written as follows: P1V1/n1T1 = P2V2/n2T2.

The molar mass of a substance is used to convert grams to moles and moles to grams. ... Molar volume allows conversions to be made between moles and volume of gases at STP. Gas density can be calculated from the molar mass and molar volume.

The "ideal molar volume" is the volume that one mole of a gas would occupy if its molecules had zero volume and no intermolecular forces of attraction. No real gas is ideal. All molecules have a volume and intermolecular forces of attraction.
