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 is the number of moles of an element determine from a known mass?
The mass of 1 mole of the element is used as a conversion factor to convert grams to 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 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.
Determine the number of formula units that are in 0.688 moles of AgNO3?
0.688 moles*6.02x1023=4.14x1023 Formula units
What number of an element can be used to determine the number of electrons in an atom?
The Atomic Number of an element is the same as the number of protons in the nucleus of an atom of that element and/or the number of electrons a in neutral atom of that element.
How is the number of moles of an element determine from a known mass?

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 will you determine the number of moles solute?
number of moles=solute concentration/solute 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.
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.
How do you find the number of carbon moles in cholesterol c27h46o?
The number of atoms of an element in a molecule is the number subscript immediately following the element symbol in the formula for the molecule. The number of moles of anything in a compound depends on the amount of the compound, which is not stated.
Determine the number of hydrogen ions when you are given 2 moles of water?
4 moles of hydrogen atoms
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
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 procedures in writing empirical formulas?
1. Determine the mass in grams of each element present, if necessary.2. Calculate the number of moles of each element.3. Divide each by the smallest number of moles to obtain the simplest whole number ratio.4. If whole numbers are not obtained* in step 3), multiply through by the smallest number that will give all whole numbers* Be careful! Do not round off numbers prematurely
Do electrons determine what kind of element an atom is?
The number of protons determine the element. It is equal to the atomic number. The number of electrons is equal to the number of protons only of the atom is neutral.
