1 mole of silver contains 6.022 X 10^23 atoms
62 moles of silver contains 3.73 X 10^25 atoms of silver
molar mass of sodium = 23 number of mols = mass/ molar mass therefore 46g of Na = 2 mol
62°F = 16.7°C(62°F - 32) multiplied by 5/9 = 16.7°C
62 degrees Fahrenheit is about 16.67 degrees Celsius
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.
62 degrees F is 16.7 degrees C , thatβs cool but ok for sleeping
There are 9.33 moles of carbon in 5.62 atoms of carbon.
== 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.
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.
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?'
I would say about 62 times

Balance this combustion reaction first! 2C4H10 + 13O2 -> 8CO2 + 10H2O 0.86 moles C4H10 (13 moles O2/2 moles C4H10) = 5.6 moles of oxygen required ----------------------------------------

It is a designation of silver content in jewelry. It means it has 92.5% of pure silver.
