You would take your grams divided by the FW (formula weight) of the molecule.
example: 1g of H2O divided by 18 = .056mol H2O
you find the formula weight by adding of the atomic masses of each element
O=16 and H=1 1(2)+16=18
You can use the molar mass of the substance to convert moles into grams. This involves multiplying the number of moles by the molar mass of the substance, where the molar mass is expressed in grams per mole. This relationship allows you to convert between the two units.
The value of the conversion factor depends on the units used to express the quantity being converted. Different units require different conversion factors to relate them accurately. The conversion factor is determined by the relationship between the original unit and the desired unit in the formula for the specific substance.
The molar mass of an element is used in a conversion factor to convert moles to grams. By multiplying the number of moles by the molar mass, you can calculate the mass of the element in grams. This conversion is important for determining the amount of substance present in a given sample.
For this you need the atomic (molecular) mass of CO2. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. CO2=44.0 grams454 grams CO2 / (44.0 grams) = 10.3 moles CO2
To do this, you need to know the molecular weight of the element you're dealing with, by adding up the atomic weights of the elements involved (found on any periodic table). The molecular weight is the mass in grams of the compound in one mole - this will provide you with a conversion factor. So take the measurement in grams and divide it by the molecular weight to convert to moles. Really what you're doing is multiplying the number by 1 mole, and dividing it by the equivalent of one mole, the molecular weight. That's the thought process behind unit analysis and how you get your "units to cancel".In this case, the answer is about 12.33 moles carbon monoxide.
The conversion factor from grams per liter (g/l) to moles per liter (mol/l) is the molar mass of the substance in grams per mole.
The conversion factor from grams per mole (g/mol) to moles per liter (mol/L) is the molar mass of the substance in grams divided by its density in grams per liter.
The mass of 1 mole of the element is used as a conversion factor to convert grams to moles
the molar mass 1 mole = xxx grams based on the chemical formula Ex: CO2 ... the atomic mass of carbon is 12, and the atomic mass of oxygen is 16 but the molar mass = (1 x 12) + (2 x 16) because of the number of atoms of each in the formula. molar mass = 44. so 1 mole = 44 grams ... turn this fact into a conversion factor. 44g / 1mole is the conversion factor to convert moles of carbon dioxide into mass (grams). Each substance will have a different molar mass, so a different conversion factor.
The conversion factor for sodium is its molar mass, which is ~22.99 g/mol. To convert mass to moles, you divide the given mass by the molar mass of sodium.
The quantity that serves as a conversion factor between mass and number of moles is the molecular mass.
Molar mass is a property of a single substance and is not inherently a conversion factor. To use it as a conversion factor, you would need to relate it to other units (e.g., grams to moles) through Avogadro's number. It serves as a bridge between the macroscopic scale (mass) and the microscopic scale (number of particles) in chemistry.
First, you would need to use the stoichiometric ratio between the reactants and the product to determine the amount of CO2 produced. Start by calculating the moles of CH4 using its molar mass as a conversion factor, then use the balanced chemical equation to determine the moles of CO2 produced from the reaction. Finally, convert the moles of CO2 to grams using its molar mass.
The conversion factor you need for this problem is the atomic mass of titanium.47.9 gram titanium = 1 mole titaniumSince you want to end up in units of grams of Ti, this goes in the numerator (on top). You want to convert from moles Ti, so this goes in the denominator (on the bottom).moles Ti47.9 gram Ti = grams Ti1 moles Ti
You can use the molar mass of the substance to convert moles into grams. This involves multiplying the number of moles by the molar mass of the substance, where the molar mass is expressed in grams per mole. This relationship allows you to convert between the two units.
The value of the conversion factor for a substance depends on its molecular weight or molar mass, which is determined by the sum of the atomic weights of its constituent elements. Additionally, the conversion factor may also take into account the specific units being used (such as grams to moles) and the physical state or form of the substance. Accurate conversion factors are essential for stoichiometric calculations in chemistry.
The conversion factor you need for this problem is the atomic mass of germanium.72.6 gram germanium = 1 mole germaniumSince you want to end up in units of moles of Ge, this goes in the numerator (on top). You want to convert from grams Ge, so this goes in the denominator (on the bottom).grams Ge1 mole Ge = moles Ge72.6 gram Ge
