What is the mass of one hydrogen deuterium atom in grams?
Approximately 2 / (6.022 x 1023) = 3.32 x 10-24 grams
How many protons and electrons does Neptunium have?
Neptunium is a chemical element with the symbol Npand atomic number 93.So it has 93 protons and the neutral atom has also 93 electrons.It is a radioactive metallic element, the first transuranic element and it belongs to the actinide series. Its most stable isotope is 237Np, with 237-93=144 neutrons
Is sodiums weight about 3 grams?
You can have any weight of sodium you want down to 0.00000000000000000000003847 grams, the approximate weight of one sodium atom
How many electrons in 2.9 grams of copper?
i havent got an elements table in front of me but here is how you do it: figure out how many moles is 2.9 grams of copper by using molecular wieght, then simply multiply so: No of moles* No of atoms in one mole* number of electrons in one atom of copper (which is the same as the No of protons...)
How many protons are in one atom of silicon?
There are 14 protons in one atom of Silicon
What do you mean by 1 atom of Carbon and 1 gram atom of Carbon?
One atom of carbon is one atom of carbon. One gram atom of carbon is the atomic weight (14 in the case of carbon) in grams, so it would be 14 grams of carbon.
Neptunium's only naturally occurring isotope 237 93Np decays by emitting one alpha particle one beta particle and one gamma ray What is the new atom formed from this decay?
Neptunium 237 is not a natural occurring isotope; all the isotopes of neptunium are artificially obtained. The new isotope formed by decay of Np 237 is protactinium 233.
What is the mass of one hydrogen deuterium atom in grams?
Approximately 2 / (6.022 x 1023) = 3.32 x 10-24 grams
What is the mass of one atom of chlorine?
35.5 grams per mole or 5.90*10^-23 for a single atom

What is the mass in grams of one atom of copper?
The periodic table states that the molar mass of copper is 63.546 grams per mole. That means that if you have one mole of copper, it will weigh 63.546 grams. One mole is 6.022x1023 (Avogadro's number) atoms. To find the mass of one copper atom in grams, you simply divide copper's molar mass by the number of atoms in one mole. 63.546 / 6.022x1023 = 1.055x10-22 One atom of copper weighs 1.055x10-22 grams.

You can have any weight of sodium you want down to 0.00000000000000000000003847 grams, the approximate weight of one sodium atom
Average mass of one atom of an element?
what is the atomic mass of an element : atomic mass is equal to the number of protons and number of neutrons present in an element
One mole of boron has a mass of how many grams?
10.81g This is found by looking at the atomic weight. The atomic weight refers to the mass of a singe atom in units of AMU (atomic mass units) and it also refers to the mass of one mole of the element in grams.
If 16g of oxygen contains 1 mole of oxygen atoms calculate the mass of one atom of oxygen in grams?
1
