76.2 mol Ag
You take 4.59 times 10 to the 25th and divide it by 3.002 times 10 to the 23. That should equal 76.47.
0.74559946861508 assuming you meant 10^23 instead of 1023
4.49 / 6.02 moles = 0.746 mole particles (of any kind), since NA = 6.02*1023 particles (of any kind) per mole, this is Avogadro's number.
1 mole Ag = 6.022 x 1023 atoms Ag
4.49 x 1023 atoms Ag x 1mol Ag/6.022 x 1023 atoms Ag = 0.746 mole Ag
The answer is 76,22 mol Ag.
The answer is 0,746 moles.
76,22 moles silver
76.2 mol Ag
each mole has avogadro's number of atoms in it, which is 6.02 x 10 to the 23rd power. so, 4 x 6.02 x 10 23 power of atoms
3.7 moles sodium (6.022 X 10^23/1 mole Na) = 2.2 X 10^24 atoms of sodium
2.16 X 1024 atoms lead (1 mole Pb/6.022 X 1023) = 3.59 moles of lead ==============
6.55 * 1024 atoms = ? moles of carbonTake the number of atoms and divide it by Avogrodos constant (6.02 * 1023). Note that if you are looking to have your units cancel, multiply the number of atoms times 1 mole and divided by atomic mass. But if you know why it is just multiplied by one, there is no reason to put it in the formula.6.55 * 1024 atoms / (6.02 * 1023) = 10.9 molescarbon
2 (atoms N / molecule N2) * 8.5*10+24 (molecules N2) / 6.02*10+23 (atoms N / mole N-atoms) = 28 mole N-atoms
H2O is water. One mole of water contains 2 moles of hydrogen atoms. Therefore, 10.7 moles of water contain 21.4 moles of hydrogen atom.
The answer is 3,587 moles.
The answer is 0,465 moles.
each mole has avogadro's number of atoms in it, which is 6.02 x 10 to the 23rd power. so, 4 x 6.02 x 10 23 power of atoms
3.7 moles sodium (6.022 X 10^23/1 mole Na) = 2.2 X 10^24 atoms of sodium
15 moles3 moles potassium3 moles nitrogen9 moles oxygen15 X 6.022 X 10 to the 23rd power
each mole contains 6.022*10(raised to the power 23) so three moles of sodium contain 18.066*10(raised to the power 23) mass of one mole of sodium is 11 grams so mass of three moles of sodium is 33 grams
5.22 x 10 to the power of 22 iron atoms is equivalent to 0,087 moles.
2.16 X 1024 atoms lead (1 mole Pb/6.022 X 1023) = 3.59 moles of lead ==============
First you need to find the atomic mass of magnesium, 24.3 grams.Then you can do a simple conversion:Grams ÷ Atomic mass = Moles7.5 grams ÷ 24.3 grams = 0.309 moles Mg
The answer is 6,31 moles Ag.
One mol of copper is 6.02 x1023 atoms. So 3.44 x 1023 would be 0.571 moles.
