By definition, one mole would be the same as the Atomic Mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Carbon's atomic mass is 12.011 grams.
For this you need the atomic mass of C. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.
7.003 grams C / (12.0 grams) = .584 moles C
About a fourth of the standard mole value.
3 grams carbon (1 mole C/12.01 grams)
= 0.2497 moles carbon
======================as I said, 0.25 moles. Or, call it 0.3 moles for sigi figi accuracy.
0.54 moles of atoms are in 7.00 grams of Carbon 13. The formula used to calculate the number of moles of atoms is No. of moles = Mass divided by Relative tomic Mass or 7 divided by 13.
100 grams carbon (1 mole C/12.01 grams)
= 8.33 moles of carbon
------------------------------
7,2 kg = 7 200 g; atomic weight of carbon = 12,0107 7200/12,0107 is approx. 600 moles.
12,0107 g/mole.
12.1 divided by 27.1 = 0.446 g
The mass in grams of 3,20 moles of copper is 158,865 g.
Balanced equation. C + O2 -> CO2 22.2 grams carbon (1 mole C/12.01 grams)(1 mole CO2/1 mole C) = 1.85 moles carbon dioxide produced -------------------------------------------------
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
1 mole Al(CN)3 = 105.03g _ moles = 163g 1 mole Al(CN)3 * 163g / 105.03g 163 moles/105.03 = 1.55 moles
The approximate molar mass of Al(OH)3 = 27 + 48 + 3 = 78 g/mol150 g x 1 mol/78 g = 1.92 moles
80,0 moles of CO2is equal to 3 520,8 g.
6,1x10-3 moles of carbon 36,7350592277.1020 atoms.
in dimensional analysis (for chemistry) your usually converting substances to moles or grams to figure out whatever you need for the problem. For units, you always want the units to cancel out as 1/7 * 7 cancels out to 1/1 or 1.for example, if i want to find the molar mass of 3.00 moles of Carbon (C), this is your set up:(3.00 moles Carbon)(36.03 grams Carbon/1mole Carbon)=108.09/1 grams Carbon=108 grams Carbon(using sig. figs)in the problem above, since moles are the numerator, and you want to find how many grams are in 3 moles of carbon, you want to set up a ratio of moles per grams. Ratios can be flip flopped based on which units you need. So i look at the periodic table and see there are 12.01 grams per 1 mole, setting the ratio up so that when it multiplies 3 moles of carbon, the moles cancel and im left with grams of carbon, the units i want. It seems complicated but gets easier with practice.
380.7 grams of iodineis equivalent to 3 moles.
The mass in grams of 3,20 moles of copper is 158,865 g.
The questions asks how many moles of carbon atoms.Molar mass is defined as the mass of one mole of a substance or in this case 6.022x1023 atoms of carbon. So the molar mass for carbon is 12.0 g/mol. Therefore the number of moles of carbon atoms is just 36/12.0 = 3.0 moles of carbon.How many atoms are in 36 grams of Carbon?[36 (gC) /12.0 (gC/molC)] * 6.02*10+23 (atoms C/molC) = 1.8*10+24 atoms in 36 g Carbon
4.3 moles of AI(CN)3 have 451,5 grams.
54,0 grams of water is equivalent to 3 moles.
3 moles of ammonia is 51grams. One mole is 17 grams.
3 moles of calcium is equivalent to 120,234 g.
Balanced equation. C + O2 -> CO2 22.2 grams carbon (1 mole C/12.01 grams)(1 mole CO2/1 mole C) = 1.85 moles carbon dioxide produced -------------------------------------------------
There are 0.75 moles in it.You have to devide 12 by molecular mass
