What is the atomic mass of an atom with 23 protons 24 neutrons and 25 electrons?
An element's core properties are determined by the number of protons. 21 protons makes this element Scandium. The number of neutrons that Scandium has is 23 in its normal state. It makes this an isotope of Scandium.
What is the mass of 1 gallon of mercury?
quart is a unit of volume, so it can not be converted into weight (Kilogram or pounds)
speaking in terms of volume:
1 US quart = 0.946352946 liters
1 gallon of water weighs 8 pounds; therefore 1 quart of water weighs 2 pounds.
What is the mass of a typical barge?
It could be argues that there is no "typical" barge. Barges range in size from small ones used on canals to large floating "tubs" that are filled with grain or other cargo. But, fortunately, our friends at Wikipedia have a "related" answer: a typical barge measures 195 feet by 35 feet (59.4 meters by 10.6 meters), and can carry up to 1500 tons of cargo. The light tonnage (empty weight) was not given, but this barge might weigh in the neighborhood of 650 tons. Need a link? You got it.
Is mass number the same as atomic number?
No. Atomic number refers to the number of protons present in the nucleus of the atom whereas mass number refers to the sum of the number of protons and neutrons in the nucleus.
For example, the isotope lithium-6 has an atomic number of 3 (for 3 protons) and a mass number of 6 (for 3 protons and 3 neutrons).
Carbon atom with atomic no of 6 and atomic mass of 12 considered isotopes of one another?
No. A carbon atom has both an atomic number and an atomic mass. All carbon atoms have an atomic number of 6. The most common carbon atom has an atomic mass of 12. See the Related Questions for more information about carbon, isotopes and atomic number and atomic mass.
Go to Answers.com and punch in "carbon isotopes" and it will show you various isotopes and the atomic mass (u) associated with each (shown as isotopic mass).
What is a large post micturition residual with prostatic mass of 40gms?
I think it means that you retain fluid after you pee. I had a Ultra sound and was told there was a 'large post-micturition residual (vol125ml) Looked up micturition and it means pass urine. Hope this helped
The mass number of an atom is equal to?
The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the symbol "A."
What is the mass number of an atom?
A mass number is the total number of protons and neutrons found in an atom.
To find the mass number, you must know the number of neutrons in that particular isotope of the element and then add the atomic number (same as the number of protons) to it.
When this number is definite it is called a nuclide and the symbol is written with a superscript giving the mass number and a subscript giving the atomic number (number of protons) placed in front of atomic symbol: 2311Na. It can also be written after the elements name, sodium-23.
Do not confuse this with the atomic number, which is the number of protons.

79Br 78.91834 50.69
81Br 80.91629 49.31
therefore:
Atomic mass of bromine element = 78.91834x0.5069+80.91629x0.4931= 79.904
What does mass consumerism require?
Mass consumerism requires high levels of production, widespread distribution networks, effective advertising and marketing strategies, and a constant demand for goods and services to be met. It also relies on disposable income, consumer culture, and a desire for material possessions.

What is the mass of ytterbium?
The atomic mass of ytterbium is approximately 173.04 amu (atomic mass units).
What are the things that can be determined using the periodic table?
Here are some things you can determine about an element using the periodic table. Not all periodic tables have the same information though.
Look at the Web Links to the left for some links to very good periodic tables that have lots of useful information! Also the Related Questions to the left have lots more information about the periodic table and what it can tell you about the elements.
Almost all periodic tables tell you the following information
-- the element's name
-- the symbol for an element's name
-- the number of protons in the nucleus of the element, which is the same as the atomic number of the element
-- the number of electrons in the element, which is also the same as the number of protons for a neutral element.
-- the name of the group (vertical column) the element is found in
Some periodic tables tell you:
-- the atomic weight of the element
-- the electron configuration of the element
-- the common oxidation states of the element
-- the electronegativity of the element
-- the melting point of the element
-- the boiling point of the element
-- the the element is a metal, non-metal or semi-metal
-- if the element is a gas, solid, or liquid at room temperature
-- if the element is synthetically prepared or naturally occurring
-- the density of the element
-- the crystal structure of the element
beat that!!!
What is the atomic mass of hydrogen-1?
The molecular mass of a molecule is just the sum of the masses of each atom in it. So if water has a mass of 18, and hydrogen has a mass of 1, and there are two hydrogens and one oxygen in water (it has formula H2O), than oxygen must weigh 16. That is:
18 - (2*1) = 16
You can also look at a periodic table, and it will tell you the mass of every element without doing any calculations! See the Web Links to the left of the answer.
How do you solve mass mass problems?
to solve for mass u divide force by acceleration . to find force u multiply mass and acceleration and to find acceleration u divide force by mass , force is measured in newtons (N) and mass is measured in meters per second squared ( m/s^2) and acceleration is measured in kilograms ( kg) .
What is the atomic number of cobalt?

What is the atomic number of Carbon?
The atomic number of carbon (C) is 6.
The atomic weight of C is 12.011 grams per mole.
The atomic number of an element is the number of protons in the element. Carbon has 6 protons and therefore has an atomic number of 6

Importance of mass communication?
Mass as indicated refers to a large number of people heterogenously dispersed around the globe.
Communication is an oral or written conversation between two or more persons
Mass comm is important in a way dat it creates a global connection around the world.with the use of mass comm/media different persons can listen to a news at a particular time in different place
As a field of study,it improves ones communicating skills, and also can be use to get jobs in respective place such as:news casting, journalism, pesenter,e.t.c.
