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 is the number of moles of an element determined froma known mass?
the molar mass is used as a conversion factor to convert grams to moles
How is the number of moles of an element determined from the 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 is a mass of a compound determined the number of moles?
The molar mass of a compound is equal to 1 mol.
How many moles of SO2 are present in 250.0 g?
Number of moles is determined by dividing molar mass into the number of grams. SO2 has a molar mass of 64.066 g. To find the number of moles in 250.0 g of SO2, divide 250.0 g by 64.066 g. This gives you just over 3.9 moles.
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
Formula for moles?
number of moles = mass of the material/molar mass
How will you determine the number of moles solute?
number of moles=solute concentration/solute molar mass
Where can you find a solution to problem solving number of moles in a given element?
Number of moles = Mass of the sample in g/Molar mass in g
Atomic mass is determined by the number of protons plus the number of?
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
