There are 6.02x1023 atoms in one mole of any substance. This number is a constant known as Avogadro's number. Check it out on wikipedia here...http://en.wikipedia.org/wiki/Avogadro%27s_number. As far as calculating your answer, just multiply and don't lose track of your decimal places.

Vanadium forms four different oxides in which the percent by mass of vanadium is respectively 76 percent 68 percent 61 percent and 56 percent what is thire formulas?
Mass V = 76 g moles V = 76/ 51 g/mol=1.5 moles O = 100 - 76/ 16= 1.5 VO Moles V = 68/51 = 1.3 Moles O = 100-68/16=2 1.3/1.3 = 1 =>V 2/1.3=1.5 =>O multiply by 2 to get whole numbers V2O3 moles V = 61/51=1.2 moles O = 100-61/16=2.4 VO2 moles V = 56/51=1.1 moles O= 100-56/16= 2.75 1.1/1.1= 1 => V 2.75/1.1= 2.5 =>O to get whole numbers multiply by 2 V2O5
How many protons are there in a silver atom?
47 protons, 47 electrons and 61 neutrons
How many neutrons are in silver -108?
108 - 47 = 61 neutrons 47 = atomic number of silver = number of protons
If the element Ag had a mass number of 108 how many neutrons would it have?
As silver atoms have 47 protons, the given isotope has 61 neutrons.
How many nutrons are in silver?
There are about 61 neutrons in silver. It actually has less electrons and protons than neutrons, since it only has 47 of them.
What is thew mass of AlBr3produced when 31.0g of Al is combined with 97.5g of bromine?
The chemical equation is 2Al+3Br2 --> 2AlBr3 So find the number of moles of the aluminum and bromine. Moles of aluminum = 31 g Al/ 27 g/mol = 1.15 moles Moles of bromine = 97.5g/ 159.8 g/mol = .61 moles Then you find the limiting reagent by dividing the number of moles of each substance by their coefficient. 1.15 moles Al / 2 = .575 .61 moles Br / 3 = .203 That means that .203 *2 moles of AlBr3 was produced, because once the Br reactant runs out, the reaction stops and you cannot get anymore of the product. So .406 moles of AlBr3 multiplied by the molecular weight of AlBr3, 266.7 g/mol, yields 108.28 grams of AlBr3
