How many grams are in 6.2X1022 atoms of gold?
I assume you mean 6.2 x 1022, but the logic is the same for other amounts anyway. 6.2 x 1022 atoms is 0.01295 moles (using Avogadro's number) 1 mole gold weights 197 grams (many periodic tables list this in the top right corner) Therefore your gold weights 197 x 0.01295 = 2.6 g
How many atoms are present in 41.23 grams of sodium?
molar mass of sodium = 23 number of mols = mass/ molar mass therefore 46g of Na = 2 mol
Sodium will react with oxygen to form sodium oxide. Use the formula below to determine how many grams of sodium oxide will be formed if 46 grams of sodium are used in the reaction.?
62 grams a+
Sodium will react with oxygen to form sodium oxide Use the formula below to determine how many grams of sodium oxide will be formed if 46 grams of sodium are used in the reaction?
The balanced equation for the reaction is: 4 Na + O2 -> 2 Na2O. From the equation, 4 moles of sodium will react to form 2 moles of sodium oxide. Calculate the molar mass of Na2O (sodium oxide) to find out how many grams will be formed.
What is the mass of 0.25 moles of nitrate ions?
I believe it would be 15.5 g. I am a beginner in Chemistry so please do not blame me if my answer is wrong. Here's my solution: Nitrate Ion is NO-3. Nitrate , Nitrogen, has an atomic mass of 14. Oxygen has 16, and since there's 3 of it, 16 x 3 =48 So we add them up to get their atomic mass : 48 + 14 = 62 From there I guess we should just times there all together. DO CORRECT ME IF I AM WRONG! 0.25 mol x 62 = 15.5 g.
How many moles of carbon are in 5.62 atoms of carbon?
There are 9.33 moles of carbon in 5.62 atoms of carbon.
A silver sample contains 52 atoms each having 60 neutrons and 48 atoms each having 62 neutrons What is the sample's average atomic mass?
The total mass of all the silver atoms would be 10,770,65(47+60) + 35(47+62) = 10,770 The total number of silver atoms is 100, 65 + 35 = 100 Dividing the total mass by the number of atoms gives us a 10770/100 = 107.7 for an atomic mass by these numbers.
How many neutrons does the atom silver have?
== silver-107 and silver-109 have 60 and 62 neutrons, respectively. There are many isotopes of silver having a neutron count from 46 to 83.
No matter how big the size how many cuts to an atoms size?
I would say about 62 times
How many grams are in 6.2X1022 atoms of gold?
I assume you mean 6.2 x 1022, but the logic is the same for other amounts anyway. 6.2 x 1022 atoms is 0.01295 moles (using Avogadro's number) 1 mole gold weights 197 grams (many periodic tables list this in the top right corner) Therefore your gold weights 197 x 0.01295 = 2.6 g
How many grams of sodium oxide will be formed if 46 grams of sodium are use?
46 grams of sodium is 2 moles. 2 mol of sodium forms 1 mol of sodium oxide. So it makes 62 g of sodium oxide.
How many grams of P2O5 will be produced from 125 g of P?
From every two atoms of P, one molecule of P2O5 is formed. The relative formula mass of two atoms of P (phosphorous) is 62, whereas for one molecule of P2O5 it is 142. The mass of P2O5 formed is therefore 142/62 times the mass of P we started with. This comes out to 286.3g (to one decimal place).
How many moles of O2 are needed to burn 1.50 moles of C8H18?
The balanced equation for the combustion of C8H18 is: C8H18 + 12.5O2 -> 8CO2 + 9H2O From the equation, you need 12.5 moles of O2 to burn 1 mole of C8H18. So, to burn 1.50 moles of C8H18, you would need 1.50 x 12.5 = 18.75 moles of O2.
Do all atoms of the same element have the same number of isotopes?
This question is misguided. Atoms do not have isotopes. In a sample of an element there are many atoms. They will all have the same number of protons in their nuclei, that's what makes them the same element. Individual atoms may have different numbers of neutrons, if this happens they are called isotopes. For instance in silver, all the atoms have 47 protons, but some of them have 60 neutrons and some have 62. We say that silver has two stable isotopes. Perhaps your question should be 'Do all atoms of the same element have the same number of neutrons?'
When did Ron Silver die?
Ron Silver died on March 15, 2009 at the age of 62.
What is the isotopic symbol for silver with 62 neutrons?
Ag-109
