For this you need the atomic mass of Na. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.
2.1 moles Na × (23.0 grams) = 48.3 grams Na
For this you need the atomic mass of Na. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.
2.1 moles Na
This value is 9,2.10 ex.21 moles.
1.56 X 10^21 atoms of sodium ( 1 mole Na/6.022 X 10^23) = 0.00259 moles sodium or 2.59 X 10^-3 moles sodium
4.828gNa X (1 mole/22.989gNa) = .21 22.989 = atomic weight of Na
How do you find the mass ratio. And how many grams fluorine is made at decomposition.
Sodium has an atomic mass of 29.990 g/mol. This means that 124 sodium atoms have a mass of 3718.76 amu, if the isotopes follow the average. To find in grams, the following must be used: 124 sodium atoms equal 2.0598 * 10-22 moles, so 124 sodium atoms have a mass of 6.177 *10-21 grams.
One mole of any element or conpound is equal to its atomic mass in grams. The atomic mass of Li is 7 AMU so 1 mole is 7 grams. So there are three moles of Li in 21 grams
Balanced equation first. 2Na + Cl2 -> 2NaCl 35 grams NaCl (1 mole NaCl/58.44 grams )( 1 mole Cl2/2 mole NaCl )( 70.9 grams Cl2/1 mole Cl2) = 21 grams of Cl2 needed
21 pounds = 9,525.44 grams
21 ounces = 595.34 grams.
21 ounces is 595.34 grams
21 ounces = 595.34 grams.
21 grams = about 0.0463 pounds.
1 gram = 10 decigrams so 21 grams = 21*10 = 210 grams. Simple!

If the reaction were 2AlCl3 + 3Pb ---> 3PbCl2 + 2Al, then from this balanced equation, 14 moles of AlCl3 would produce 3/2 x 14 moles of PbCl2 = 21 moles of PbCl2.
1000 grams = 1 kilogram so 21 g = 21/1000 = 0.021 kg. Simple!
Answer: 21 g = 0.046297 lb
