How small is a quarks?
Quarks can actually vary greatly in size. The most common types of Quarks are Up and Down (scientists are not the most creative when it comes to names) and they have the mass of about 1/400 and 1/200 (respectfully) the mass of a proton. But some quarks, like the Top quark (another uncreative name) has the mass of the entire Tunston atom.
How many neutrons are in an atom of 18O?
An atom of 18O has 10 neutrons. This is calculated by subtracting the atomic number (which is 8 in this case) from the atomic mass number (18).
How much energy is in the mass of a 60 kilogram person?
It is a fairly simple conversion, since you are already in the right mass unit. 60 kg*(299,792,458m/s)^2 works out to 5.39*10^18 joules of energy, equivalent to 1.29 gigatons of TNT or about 86,000 Hiroshima bombs.
How much mass would one molecule of water have?
The mass of any molecule is equal to the sum of the Atomic Mass Units of all of its constituent atoms. Atomic Mass Unit values may be found on any Periodic Table. In this case, a water molecule consists of two Hydrogen atoms and one Oxygen atom. Hydrogen has a mass of approximately 1 AMU. Oxygen has a mass of approximately 16 AMU. Therefore, the mass of one molecule of water is approximately 18 AMU (or 18.01528 AMU exactly). What does this number mean? If you had exactly 6.022 x 10^23 molecules of water, it would weigh 18 grams.
What is 4432000000000000000 in scientific notation?
It is: 4.432*10^18 in scientific notation
How many neutrons if number of protons is 18 mass is 37.8?
there is amount of proton = amount of electron and the mass = amount of proton + amount of neutron so we take the mass - amount of pronton we will get the amount of neutron =20.8
Are Quarks about one half the diameter of a proton or neutron?
No. Quarks can be described as "sizeless" because their mass is based on their energy, and even a proton's mass is not exactly equal to the mass of the constituent quarks (gluon mass is involved). The "volume" occupied by a quark (if it existed, uncombined) also varies by quark type.* An upper size limit has been proposed of about 1 x 10^-18 m, that is, less than one thousandth of the diameter of a proton.
What are the release dates for Jimmy Kimmel Live - 2003 10-167?
Jimmy Kimmel Live - 2003 10-167 was released on: USA: 18 May 2012
There are 10 neutrons and how many electrons in an atom of oxygen-18?
Because the world is made up like this. Well, a 18O, as it's name shows, has a releatve mass of 18 units. A proton has got a mass of 1 ,a neutron ahd got a mass of 1, and electron has gor a amss of 1/1840 (we dont calculate with a this small mass). So in a 18 relative mass, neutrons + protons = 18. As oxygen is the 8th in the periodic table, it has got 8 atoms. So neutrons + 8 = 18, where neutrons = 10.
What is 167 over 18 as a mixed number?
167/18 = 9 and 5/18.
How many times does 18 go into 167?
167/18 = 9 and 5/18, so 18 goes into 167 nine times with a remainder of 5
What is the mass of oxygen-18?
As the name would suggest, the mass of Oxygen-18 is 18.
Is there a unit smaller than a microliter?
Well pico is 10^-12, so the next two are: Femtometer (10^-15, or a quadrillionth) Attometer (10^-18 , or a quintillionth) An attometer is smaller than anything known, and(To my knowledge), there is no measurement smaller yet.
How many proton in a coulomb?
One coulomb is equal to the force of repulsion when a unit positive charge is placed from a similar charge at a distance of 1m.
What is 18 plus 18 plus 18 plus 19 plus 23 plus 23 plus 24 plus 24 equals?
18+18+18+19+23+23+24+24=167

If you have 6.02 x 1023 molecules of H2O. What is the mass of this sample?
The molar mass of water (H2O) is approximately 18 g/mol. To find the mass of 6.02 x 10^23 molecules, you would divide by Avogadro's number (6.02 x 10^23) and then multiply by the molar mass of water. This would give you a mass of approximately 18 grams.
