The relationships between formula mass, the mole, and Avogadro’s number can be applied to compute various quantities that describe the composition of substances and compounds. For example, if we know the mass and chemical composition of a substance, we can determine the number of moles and calc...

volume conversions molar mass – formula it is all very well to calculate the atomic molecular and formula masses of atoms, molecules , and other compounds, but since we cannot weigh an individual particle, these masses have limited usefulness. to make measurements of mass useful we must express...
This is a calculator to convert from concentration, volume, and molecular weight to mass. The calculator can be used to find the mass, volume, or concentration needed to create a solution using a substance with a specific molecular weight.
Find the gram formula mass of 1 moles of KAl(SO4)2· 12H2O. Remember, multiply the values of atomic mass units of atoms times their subscripts. Coefficients are multiplied by everything that follows. For this example, that means there are 2 sulfate anions based on the subscript and there ...
Moles of AgBrO3=0.0072 g236 g/mol=3.05×10−5 mol Step 2: Calculate the molarity (M)Since the solubility is given for 1000 mL, we can directly convert moles to molarity:Molarity (M)=molesvolume (L)=3.05×10−5 mol1 L=3.05×10−5 M Step 3: Write the dissociation equationThe...
The molar mass can be computed if the mass and the volume of the gas are also known.Molar Mass of Gas The molar mass is the amount of mass present in one mole of any substance. The number of moles gives information about the number of elementary species in a given sample, like atoms...
For this problem, you could use a ratio between the original number of moles, the original volume and the final number of moles in order to find the final volume.Volume units do not need to be standardized because the problem does not require the ideal gas formula.In the end. n1/V1=...
