4,96 x 1024 molecules of glucose is equal to 8,236 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)
6.022 x 1023 x 2 = 1.2044 x 1024
If it is 1.54 moles of Br atoms then the answer is 9.274 X 1023 atoms.If it is 1.54 moles of Br2 molecules then the answer is 1.855 X 1024 atoms.
Each glucose molecule contains 6 carbon atoms. Thus we need 18 molecules of CO2 to make 3 molecules of glucose.
The equivalent is two moles.
The answer is 4 moles.
1.204 x 1024
The answer is 15 moles.
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 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.
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
2.10 moles carbon dioxide (6.022 X 1023/1 mole CO2) = 1.26 X 1024 molecules of carbon dioxide ==============================
The value is 1,328.10e-3 moles.
Glucose has a molar mass of 180. There are thus 0.1 moles present in 18 g. 1 mole contains 6.022 x 1023 molecules. 0.1 moles contains 6.022 x 1022 molecules and so glucose with 24 atoms per molecule contains 24 x 6.022 x 1022 = 1.44528 x 1024 atoms.
4.26mol x ( 6.022 x 1023 molecules / 1mol ) = 2.565 x 1024 molecules
6.022 x 1023 x 2 = 1.2044 x 1024
