How is the number of moles of en element determined from known mass?
The number of moles of an element can be determined using the formula: moles = mass (grams) / molar mass (grams per mole). First, you need to find the molar mass of the element from the periodic table. Then, divide the known mass of the element by its molar mass to calculate the number of moles. This allows you to convert the mass into an amount expressed in 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 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 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 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 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.
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 would we know how many moles are in a certain element?
number of moles = mass of the element/molar mass of the element
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.
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 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 can one determine the empirical formula from moles in a chemical compound?
To determine the empirical formula from moles in a chemical compound, you first need to find the moles of each element present in the compound. Then, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio. This ratio represents the empirical formula of the compound.
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 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.
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 to determine the empirical formula of a compound?
To determine the empirical formula of a compound, you need to find the ratio of the elements present in the compound. This can be done by analyzing the mass percentages of each element in the compound and converting them into moles. Then, divide the moles of each element by the smallest number of moles to find the simplest whole number ratio. This ratio represents the empirical formula of the compound.
