What is the rounded mass number of Argon?
Argon is a non metal element. Mass number of it is 40.
Can mass only be a whole number?
No, it cannot. A whole number is a quantity without units - a pure number. A mass of 1 pound is a whole number of pounds but it is 0.45359 kilograms: not a whole number, or 453.59 grams, again not a whole number.
Does the mass number of an element have to be a whole number?
Approximately, yes. But the mass number is an average of the masses of the isotopes of the element, weighted together according to their abundance. This averaging of different whole numbers results in the mass number not being a whole number.
What is the mass in kilograms of a sculpture that weighs 570 lb rounded to the nearest tenth?
570.0
What is the atomic mass rounded of boron?
Boron - B - Group IIIThe atomic number is 5.The mass number is 11.
What is 4.00260 rounded to in atomic mass?
It is 4.0026 : the atomic mass can be a fraction.
What is the molar mass of CO2 rounded to the nearest whole number?
The answer is simple it's one/1
What is the nearest whole number of atomic mass of potassium?
The nearest Whole number of atomic mass of potassium is 69
Do you round atomic mass 30.97?
Yes, the atomic mass on the periodic table is usually rounded to the nearest whole number, so an atomic mass of 30.97 would be rounded to 31.
If you round the average atomic mass to the nearest whole number so whats neons atomic weight?
Neon's atomic weight, rounded to the nearest whole number, is 20.
What is zinc atomic weight to nearest whole number?
The atomic weight of zinc to the nearest whole number is 65.
How can you solve of number of neutrons?
You can determine the number of neutrons in an atom by subtracting the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). This will give you the number of neutrons in the atom.
What element has an atomic mass of 32.06?
Sulfur- Element Number 16 on the Periodic Table of Elements
The mass number of an elements is equal to?
The mass number of an element is equal to the total number of protons and neutrons in its nucleus. It is rounded to the nearest whole number on the periodic table.
The mass number of an element is equal to what of an element?
The mass number of an element is equal to the total number of protons and neutrons in the nucleus of an atom of that element.
Why are atomic masses rounded?
Sometimes the atomic mass is listed as the average mass of the isotopes and contains a decimal. But since you can't have a fractional part of a proton or a neutron without creating a big mess, it is necessary to round to the nearest whole number. Subtracting the atomic number from the rounded atomic mass will give you the number of neutrons.
What is the molar mass of H2O to the nearest whole number?
18g/mol
