The answer is B, 8.0 x 10^1
There are 6.023 x 10^23 atoms in one mole, of any substance. So simply divide 4.8 x 10^25 by 6.023 x 10^23, to get about 79.69 which if you convert into scientific notation, is about 8.0 x 10^1
the answer for me was A but that's on novanet
4.8 X 10^25 what????????? I assume you mean atoms, but units are important because there is no such thing as mind reading!!!!
4.8 X 10^25 atoms tungsten (1 mole tungsten/6.022 X 10^23)
= 80 moles of tungsten
Quite a few moles here!
4.8 X 1025 tungsten atoms (1 mole tungsten atoms/6.022 X 1023)
= 79.7 moles of tungsten atoms
------------------------------------------( call it 80 moles )
One mole of a substance contains the same number of particles as the Avogadro constant, which is 6.02*1023.
In short, 1 mole = 6.02*1023 particles
4.8*1023 particles / 6.021023 particles/mol = 0.797 mol
The answer to this kind of question is the same for any atoms: Divide the given number by Avogadro's Number, which is the number of atoms in one mole. In this instance, there are (4.8 X 1025)/(6.022 X 1023) or 80 moles, to the justified number of significant digits
There are 6.022 E23 atoms in one mole, per Avogadro's number. Then 4.8 E25 atoms is equal to 79.71 moles of tungsten.
There are 6.03 x 1023 molecules in one mole, so 4.8 x 1023 / 6.03 x 1023 which is about .80 moles.
The answer is 0,797 moles.
80
0,39 moles of gallium contain 2,34863493423.10e23 atoms.
The number of chlorine atoms in 2,00 moles of CCl4 is 48,113.10e23.
2,2 moles of plutonium: 13,248711938.1023 atoms.
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
0.0845 moles of tungsten is equal to 0,50887.10e23.
5,82 x 1023 atoms of tungsten equal 0,966 moles.
Not many! ( how do you people keep coming up with fractional atoms? ) 4.8 atoms tungsten (1 mole tungsten atoms/6.022 X 10^23) = 8.0 X 10^-24 moles tungsten atoms
1,638 moles contain 9,864266723766.10e23 atoms.
44 moles of atoms
20 moles
This is equivalent to 1,4 moles.
