How many moles of tungsten atoms are in 4.8x10 25 atoms of tungsten?

Answer 1

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

Answer 2

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

Answer 3

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 )

Answer 4

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

Answer 5

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

Answer 6

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.

Answer 7

There are 6.03 x 1023 molecules in one mole, so 4.8 x 1023 / 6.03 x 1023 which is about .80 moles.

Answer 8

The answer is 0,797 moles.

Answer 9

80
