One takes the Atomic Mass of that element (the number under the element on a Periodic Table, measured in amu). That number is the number of grams of the element it takes to make one mole. in other words:
X grams (of element)
(Atomic Mass of element)= --------------
1 mol (of element)

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
How many moles are in 89.0 grams of aluminum?
all you have to do to fine the moles of any element is divide the given grams by the molar mass (which you can find on a periodic table of elements) Likewise, if you need to find the grams, just multiply the number of moles by molar mass. moles = grams/molar mass grams = moles x molar mass your equation should look like this: moles = 89.0 / 17.0 moles = .471
How do you find moles of hydrogen?
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
How do you find the number of moles when you are not given the mass?
you count them
How do you convert an element to moles?
to convert an element to moles you need to setup and equation, for our example we will be using 5g of O2 or oxygen. You need to know what O2's molar mass is as well, it is 32g. So the equation would be 5g of O2 / 32 = .16 moles of O2. So to convert moles to grams all you do is multiply the moles given by the molar mass of the element/compound and you have your grams Hoped this helped : )
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 find liters in a solution when given moles?

0.871 moles is how many grams?
Multiply the number of moles by the molecular weight of the compound (or atomic weight for an element) to find the mass in grams.
How many moles of he are in 16 of the element?
There are approximately 4.0 moles of Helium in 16 grams of the element.
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 many moles of helium are in sixteen gallons of the element?
The answer is 2,7 moles.
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.
