4.5165x10^10 ions x 1 mole ions/6.02x10^23 ions = 7.5025 x 10^-5 moles
The number of Avogadro states that 1 mole equals 6.02214179*10^23 mole. So if you have 1*10^19 HCl molecules, you have: 1*10^19 / 6.02214179*10^23 = 1.660538783*10^-5 mole of HCl. Which equals 0.0166053878 milimole.
The molecular formula of allicin is C6H10OS2. The molar mass is 162.27 g mol−1. Use this fact along with the percentage of allicin in the substance to calculate the molecules of allicin.
There are about 6.24 x 1018 electrons in a coulomb. If we take 1.63 times that we get 1.02 x 1019 electrons. To "micro" that, we have to multiply it by 10-6, and that takes us to 1.02 x 1013 electrons. About.
Yes, by spontaneous fission, but the nymber of neutrons is very small because the halflife of the spontenuoes fission is: for Uranium 235: (1,0 ± 0,3).1019 years for Uranium 238: (8,20 ± 0,10).1015years
The formula for the most common form of ammonium phosphate is (NH4)3PO4.3 H2O, and its gram formula mass is 203.13. The formula shows that there are 3 ammonium ions in each formula unit. 10.7g/203.13 is 5.27 X 10-2 formula units. Therefore, the number of ammonium ions present in 10.7g of this ammonium phosphate is 3 X 5.27 X 10-2 X Avogadro's Number or 9.52 X 1019 ammonium ions, to the justified number of significant digits.
They are 1 and 9.
