How is the mass of a compound determined from the number of moles?
The mass of a compound can be determined from the number of moles by using the formula: mass = number of moles × molar mass. The molar mass, which is the mass of one mole of a substance, can be found by summing the atomic masses of all the elements in the compound as listed on the periodic table. By multiplying the number of moles of the compound by its molar mass, you obtain the total mass of the compound in grams.
How is the mass of a compund determined from the number of moles?
1 mol is equivalent to the molar mass of a compound, in grams.
How is the mass compound determined from the number of moles?
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
How is the number of moles determined from a known mass?
Number of moles = Total mass/Molar mass
How is a number of moles of an element determined from a known mass?
The number of moles is mass in g/molar mass in g.
How do you work out the number of moles of unknown compound if you are only given the molar mass?
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.
Which statement shows how to correctly convert from the mass of a compound in grams to the amount of that compound in moles?
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.
How is the number of moles of en element determined from known mass?
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.
Formula for moles?
number of moles = mass of the material/molar mass
How is the number of moles of an element determined from known 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.
How do you find the number of particles in a compound when given the 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.
What is the formula mass of a compound if 4 moles of that compound has a mass of 96 grams?
To find the formula mass of the compound, divide the total mass by the number of moles. In this case, the formula mass is calculated as 96 grams divided by 4 moles, which equals 24 grams per mole. Therefore, the formula mass of the compound is 24 g/mol.
