Multiply the number of moles times the molar mass of the compound. Moles cancel and you are left with mass in grams.
For example: What is the mass of 2.47 moles of sodium chloride, NaCl?
Known: The molar mass of NaCl is 58.44g/mol. (Using atomic weights in grams from the Periodic Table.)
Solution:
2.47mol NaCl x 58.44g/mol NaCl = 144g NaCl
The number of moles is mass in g/molar mass in g.
The number of moles of an element can be determined using the formula: moles = mass (grams) / molar mass (grams per mole). First, you need to find the molar mass of the element from the periodic table. Then, divide the known mass of the element by its molar mass to calculate the number of moles. This allows you to convert the mass into an amount expressed in moles.
number of moles = mass of the material/molar mass
To find the number of particles in a compound when given the mass, first calculate the number of moles using the provided mass and the molar mass of the compound. Then, use Avogadro's number (6.022 x 10^23 particles/mol) to convert the moles to the number of particles in the compound.
To find the number of moles of Na2SO4 in 25.0 g of the compound, you need to convert the mass to moles. First, determine the molar mass of Na2SO4, then divide the given mass by the molar mass to obtain the number of moles.
The molar mass of a compound is equal to 1 mol.
1 mol is equivalent to the molar mass of a compound, in grams.
Number of moles = Total mass/Molar mass
The number of moles is mass in g/molar mass in g.
To find the number of moles from molar mass, divide the mass of the compound by its molar mass. The formula is: Moles = Mass (g) / Molar Mass (g/mol). This will give you the number of moles of the unknown compound.
To convert from the mass of a compound in grams to the amount of that compound in moles, you need to divide the mass of the compound in grams by its molar mass (which is found on the periodic table). This will give you the number of moles of the compound. The formula to use is: moles = mass (g) / molar mass.
number of moles = mass of the material/molar mass
The molar mass is the measurement of mass per one mole of a substance. If the mass of a matter is known, divide it from the molar mass to obtain the number of moles.
To find the number of particles in a compound when given the mass, first calculate the number of moles using the provided mass and the molar mass of the compound. Then, use Avogadro's number (6.022 x 10^23 particles/mol) to convert the moles to the number of particles in the compound.
To find the number of moles of sodium sulfate in 0.1000g of the compound, you first need to determine the molar mass of Na2SO4. Then, divide the given mass by the molar mass to get the moles.
To determine the number of moles of an element from its known mass, you can use the formula: moles = mass / molar mass. First, find the molar mass of the element from the periodic table. Then, divide the given mass of the element by its molar mass to find the number of moles.
To find the number of moles of Na2SO4 in 25.0 g of the compound, you need to convert the mass to moles. First, determine the molar mass of Na2SO4, then divide the given mass by the molar mass to obtain the number of moles.
