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 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 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 of an element determined froma known mass?
the molar mass is used as a conversion factor to convert grams to moles
Formula for moles?
number of moles = mass of the material/molar mass
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 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 work out the number of moles of unknown compound if you are only given the molar mass?
The molar mass of any compound contain a number of molecules equal to the number of Avogadro:6,022 140 857(74).10e+23.
Which statement shows how to correctly convert from the mass of a compound in grams to the amount of that compound in moles?
Moles = Mass (g) x Molar mass (g)
How many moles in NaCHO3?
A mole is a defined number of atoms/molecules of an element/compound. Therefore, the number of moles of NaCHO3 will depend on the mass of NaCHO3 that you have. To calculate the number of moles in a known sample, divide the mass of the sample (in grams) by the molecular weight.
What is mass Stoichiometry?
The number of moles in the equation of B DIVIDED BY the number of moles in the equation of A ANSWER TIMES the molar mass of B OVER 1. A is the the known compound, B is the one your trying to find out.
