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 determine the number of moles in an element?
Multiply the # of grams by the element's atomic weight. Or if dealing with milliliters, multiply the volume by solutions molarity. When calculating a molecule's # of moles, multiply the # of grams by the molecular weight.
How would we know how many moles are in a certain element?
number of moles = mass of the element/molar mass of the element
Determine the number of formula units that are in 0.688 moles of AgNO3?
0.688 moles*6.02x1023=4.14x1023 Formula units
What are the steps required to find the mass of an element from a given amount of the element in moles?
The mass of 1 mole of the element is used as conversion factor to covert grams to moles. ~APEX

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 would we know how many moles are in a certain element?
number of moles = mass of the element/molar mass of the element
How do you balance equtions?
Make sure that the number of moles of each element on the left is equal to the number of moles of the same element on the right.
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.
How will you determine the number of moles solute?
number of moles=solute concentration/solute molar mass
How is the number of moles determined from a known mass?
Number of moles = Total mass/Molar mass
Can you determine the number of moles of any substance produced in a reaction if you know the number of moles of at least two of the reactants?
Yes, it is possible.
