The value is 1,328.10e-3 moles.
Avogadro's number says that there are 6.022 E23 molecules per mole. So in 8.30 E25 molecules there are 137.82 moles of water.
2.18 X 1022 molecules H2O (1 mole H2O/6.022 X 1023)
= 0.036 moles water
---------------------------
1 mole H2O = 6.022 x 1023 molecules H2O
(2.35 x 1024 molecules H2O) x (1mol/6.022 x 1023 molecules) = 3.90 moles H2O
The answer is 4 moles.
The answer is 15 moles.
2.1 X 1024 atoms (1 mole/6.022 X 1023) = 3.5 moles ========
1 mole of any substance contains Avogadro's number of particles (molecules). 6.022 x 1023 molecules / mole x 2.16 moles = 1.300752 x 1024 molecules
1 mole contains 6.022 x 1023 molecules. number of moles of CO= (4.65 x 1024) / (6.022 x 1023) = 7.72 mol The identity of the molecule does not change the answer.
4,96 x 1024 molecules of glucose is equal to 8,236 moles.
The answer is 4 moles.
1.204 x 1024
The answer is 15 moles.
3.6 moles hydrogen atoms (1 mole water/2 mole H)(6.022 X 1023/1 mole water molecules) = 1.1 X 1024 molecules of water =======================
2.1 X 1024 atoms (1 mole/6.022 X 1023) = 3.5 moles ========
Given: 7.6 x 1024 O2 moleculesKnown: 1 mole O2 molecules = 6.022 x 1023 molecules O2 moleculesConvert molecules to moles.7.6 x 1024 molecules O2 x (1mol O2/6.022 x 1023 molecules O2) = 13 moles O2 (rounded to two significant figures)
1 mole of any substance contains Avogadro's number of particles (molecules). 6.022 x 1023 molecules / mole x 2.16 moles = 1.300752 x 1024 molecules
1 mole contains 6.022 x 1023 molecules. number of moles of CO= (4.65 x 1024) / (6.022 x 1023) = 7.72 mol The identity of the molecule does not change the answer.
2.10 moles carbon dioxide (6.022 X 1023/1 mole CO2) = 1.26 X 1024 molecules of carbon dioxide ==============================
1 mole H2O = 6.022 x 1023 molecules H2O 2mol H2O x 6.022 x 1023 molecules H2O/1mol H2O = 1 x 1024 molecules H2O
