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)
What else can I help you with?
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
Do you find the number of moles of an element?
Use avagadro's number - states the number of atoms in 1 mole of a substance: 6.022 x 10^23
How is the number of moles of an element determined from the known mass?
To determine the number of moles of an element from its known mass, you can use the formula: moles = mass / molar mass. First, find the molar mass of the element from the periodic table. Then, divide the given mass of the element by its molar mass to find the number of moles.
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 can one determine the empirical formula from mass data?
To determine the empirical formula from mass data, you need to find the molar mass of each element in the compound. Then, divide the given mass of each element by its molar mass to find the moles of each element. Finally, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio of elements, which represents the empirical formula.
How can one determine the empirical formula from given percentages of elements in a compound?
To determine the empirical formula from given percentages of elements in a compound, you first need to convert the percentages to grams. Then, divide the grams of each element by its molar mass to find the moles of each element. Next, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio. Finally, use these ratios to write the empirical formula of the compound.
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 to find the volume when given molarity and moles?
To find the volume when given molarity and moles, use the formula: volume moles / molarity. This formula helps calculate the volume of a solution based on the amount of solute (moles) and the concentration of the solution (molarity).
What is the mass of 1.6 mol of the element?
To find the mass of 1.6 moles of an element, you need to know the molar mass of that element (found on the periodic table). Multiply the molar mass by the number of moles (1.6) to get the mass in grams. Thus, by multiplying the molar mass by 1.6 mol, you can find the mass of 1.6 moles of the element.
How can one determine the molecular formula from the given molar mass and percent composition?
To determine the molecular formula from the given molar mass and percent composition, you can follow these steps: Convert the percent composition to grams for each element present in the compound. Calculate the number of moles of each element using the molar mass and the grams of each element. Divide the moles of each element by the smallest number of moles to get the mole ratio. Use the mole ratio to determine the empirical formula. Calculate the empirical formula mass and compare it to the given molar mass to find the multiplier needed to get the molecular formula.
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?
To determine the number of moles of an element from a known mass, you use the element's molar mass (grams per mole). Simply divide the given mass of the element by its molar mass to calculate the number of moles. This relationship is described by the formula: moles = mass (g) / molar mass (g/mol).
