Molar mass is the mass that is occupied by one mole of any substance. Unit is g/mol.
Molar volume is the volume that is occupied by one mole of any substance. Unit is L/mol.
This is the ratio volume/time.
To calculate the ratio of effusion rates for nitrogen (N2) and neon (Ne), use Graham's law of effusion: Ratio = (Molar mass of neon / Molar mass of nitrogen)^(1/2) For neon (Ne) with a molar mass of 20.18 g/mol and nitrogen (N2) with a molar mass of 28.02 g/mol, the ratio of their effusion rates would be approximately √(20.18 / 28.02) ≈ 0.75.
To calculate the surface area to volume ratio, simply divide the surface area of the object by its volume. This ratio is commonly used in science to understand how efficiently an object exchanges materials with its environment, with a higher ratio indicating better surface area for exchange relative to its volume.
To calculate 1 millimolar (mM) concentration of a substance, you need to know the molar mass of the substance. Then, divide 1 millimole (mmol) by the molar mass to obtain the volume of the substance needed to make a 1 mM solution.
To calculate the mass of ethylene oxide needed to react with 10 g of water, you need to determine the molar ratio of water to ethylene oxide in the balanced chemical equation for the reaction. Once you have the molar ratio, you can use it to calculate the mass of ethylene oxide needed. The molar mass of ethylene oxide is 44.05 g/mol.
To calculate the molar volume of a substance, you divide the volume of the substance by the number of moles present. This can be done using the formula: Molar Volume Volume / Number of Moles.
No, the molar ratio is not necessarily the same as the volume ratio for non-gaseous reactions. The molar ratio refers to the ratio of the number of moles of reactants or products involved in a chemical reaction. It is determined by the balanced chemical equation. On the other hand, the volume ratio refers to the ratio of the volumes of reactants or products in a reaction. In some cases, the volume ratio may be equal to the molar ratio, especially for ideal gases at the same temperature and pressure. This is known as the ideal gas law and is represented by Avogadro's principle. However, for non-gaseous reactions, the volume ratio may not necessarily be equal to the molar ratio. This is because the volume of a substance is influenced by factors such as density, state (solid, liquid, or gas), and the presence of solvents or other compounds. Therefore, it is important to use the molar ratio when determining stoichiometry and reaction quantities, rather than relying solely on volume ratios.
If the gases have the same molar volume, the stoichiometric ratio would be one to one. Molar volume is the volume occupied by one mole of a substance. This indicates that there is a 1:1 molar ratio of each gas.

You measure or calculate the surface area; you measure or calculate the volume and then you divide the first by the second. The surface areas and volumes will, obviously, depend on the shape.

Molar mass is the sum of all of its elements' average atomic mass in grams. Such as: NH4 would be calculated by adding nitrogen's aam (14.007) and hydrogen's aam multiplied by four (1.0079 x 4 = 4.0316). Therefore, ammonium's molar mass would be (14.007+4.0316) 18.039. Rounded to sig figs.
