How many moles are there in 2.50 moles of sodium?
Sodium in its elemental form is just sodium metal, Na. Thus assuming that the sample of sodium is pure, there are 2.50 moles of sodium in a 2.50mol sample.
How do you make a pure sample of fluorine?
No you cannot make a pure sample of Fluorine because it is an earth made element.
What type of bonding occurs in a sample of pure sodium Na?
In a sample of pure sodium, metallic bonding occurs where the outer electron of each sodium atom is delocalized and free to move throughout the metal lattice, creating a "sea of electrons" that holds the atoms together.
Is NaCl a pure substance?
You could test a sample with a mass spectrometer, which would show all the elements present. If there are no elements present other than sodium and chlorine, then you have pure sodium chloride.
How do you make a pure sample of cobalt?

How many moles in 0.630gNaCl?
The formula mass of sodium chloride is 23.0 + 35.5 = 58.5 Amount of sodium chloride in a 0.630g pure sample = 0.0108mol
What mass of sodium would make up a 150 gram sample of sodium chloride?
Since each molecule of sodium chloride contains one sodium atom, the mass of the sodium in a 150 gram sample of sodium chloride would be the same as the mass of the sample itself, which is 150 grams.
If a sample of pure sodium has a mass of 8.2 grams and sodium has an average atomic mass of 22.99 gmol how many sodium atoms are there in the sample?
To calculate the number of sodium atoms in the sample, first find the number of moles in the sample by dividing the mass (8.2 g) by the molar mass of sodium (22.99 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. Therefore, there are approximately 2.71 x 10^23 sodium atoms in a sample weighing 8.2 grams.
Why does a sample of pure sodium need to be kept in special oil so the air can't touch it?
Pure sodium is highly reactive with air and moisture, causing it to oxidize and form a layer of sodium oxide or hydroxide. This reaction can be exothermic and can lead to a fire or explosion in the presence of air. Storing pure sodium in oil creates a barrier between the sodium and air, preventing this dangerous reaction from occurring.
What mass of sodium would make up 150 gram sample of sodium chloride?
The answer is 59,5 g Na.
How do you make a pure sample of rhodium?
i actually have no idea what im anwsering............help
What elements go with sodium to make bromine?
Sodium forms an ionic bond with bromine to make sodium bromide, which is typically represented as NaBr. This compound consists of one sodium ion (Na+) and one bromine ion (Br-), with sodium donating an electron to bromine to achieve a stable electron configuration. Sodium bromide is a white, crystalline solid that is commonly used in pharmaceuticals and photographic chemicals.
