What else can I help you with?
The molar mass of an element is equal to?
The element's average atomic mass.
What the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
To determine the subscript of an element in a molecular formula the empirical mass must be multiplied by the actual mass?
The actual mass must be divided by the empirical mass. This was derived from the following equation: (subscript)(empirical formula) = (molecular formula) subscript = (molecular formula)/(empirical formula)
What is the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
How to find the mass of an element in a chemical compound?
To find the mass of an element in a chemical compound, you can use the atomic mass of the element from the periodic table and the number of atoms of that element in the compound. Multiply the atomic mass by the number of atoms, and you will get the mass of that element in the compound.
Which is a factor in determining the average atomic mass of an element?
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
The molar mass of an element is equal to?
The element's average atomic mass.
What does an element's molar mass tell you about the element?
An element's molar mass represents the mass of one mole of that element in grams. It tells you the average atomic mass of the element, which is the sum of the protons and neutrons in the nucleus of its atoms. Molar mass helps in determining the amount of substance in moles when given the mass of the sample.
What is the rule for determining mass?
Just adapt the formula for density to find the mass of an object. After adapting it, it should be like this: Volume*Density=Mass
What the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
What is the average mass of an atom?
That depends on the atom in question. What element is it of? The periodic table should be helpful in determining atomic mass.
What is the difference between the atomic number and the atomic mass?
The atomic number represents the number of protons in an atom's nucleus, determining its chemical properties and element identity. Atomic mass is the total mass of an atom, which includes the sum of its protons, neutrons, and electrons.
To determine the subscript of an element in a molecular formula the empirical mass must be multiplied by the actual mass?
The actual mass must be divided by the empirical mass. This was derived from the following equation: (subscript)(empirical formula) = (molecular formula) subscript = (molecular formula)/(empirical formula)
What element is responsible for determining male sex in humans?
The element responsible for determining male sex in humans is the Y chromosome.
What determines an element's mass?
the mass of protons + the mass of neutrons = mass of the element
Percent composition describes the relative contribution of one element to the formula weight of the entire?
compound, expressed as a percentage. It can be calculated by dividing the molar mass of the element in the compound by the molar mass of the compound overall and multiplying by 100. This helps in determining the amount of each element present in a compound.
What does the atomic mass of an element repreasent?
The atomic mass of an element represents the average mass of an atom of that element, taking into account the abundance of its isotopes. It is measured in atomic mass units (amu) and is valuable in determining the element's properties and behavior in chemical reactions.
