6.228 mole of zinc atom
1 gram carbon (1 mole C/12.01 grams) = 0.08 moles carbon ===============
One pound-mole (lbmol) is equivalent to approximately 453.6 gram-moles (gmol).
To find the number of moles, we need to divide the given mass of cobalt (382g) by its molar mass, which is approximately 58.93 g/mol. Therefore, 382g of cobalt contains approximately 6.48 moles of atoms.
18 grams of water contain 1 mole. so 1 gram contains 1/18 moles of water.
Graphite is a form of carbon, so the question is basically asking how many moles of carbon are in 18.0 grams of carbon. One gram of carbon contains 12.01 moles. This can be found on a periodic table. 18.0 grams of carbon must therefore have 18 times 12.01, or 216.18, moles of carbon.
0,688 g calcium is equivalent to 0,017 moles.
1 atom-gram of uranium = 238,02891 grams
how many moles are in 95.0 gram of octane?
The answer is 3 moles.
1 gram carbon (1 mole C/12.01 grams) = 0.08 moles carbon ===============
0.1868 moles
The answer is 0,111 moles.
85.2 gram LiF sample is equivalent to 3,28 moles.
3.0 moles of H2O have 54 g.
27g
This is a chemical calculation. there are 3.267 moles in this solution.
It depends on the substance. Remember that moles are a unit of amount, and one mole is 6.02 × 1023 atoms. So if you have lead and hydrogen, they are obviously going to weigh differently. It would take far fewer atoms of lead to amount to 1 gram; therefore, less moles. However, one hydrogen atom has far less mass than one lead atom, and would need more atoms (and moles) to make one gram.
