5 grams Al (1mol Al/26.98g )= 0.185 mol
3,56 mol Al is equal to 96,05 grams.
SrCl2 Strontium (Sr) = 87.62 grams/mol 2 Chlorine (Cl) = 70.9 grams/mol ----------------------------------------------------add Strontium chloride = 158.52 grams/mol ============================
1.9 mol Se ( 78.96 grams/1mol Se ) = 150.024 grams
The mass in grams of 5,01 mol of xenon is 657,778 g.
5 grams of table salt is 5 grams of NaCl. NaCl has a molar mass of 58.443 grams/mol, so 5 grams would be .0855 mol NaCl. In one mole of NaCl there is one mole of Na, so there would be .0855 mol Na, or 5.235 * 1022 atoms Na.
5 grams Al (1mol Al/26.98g )= 0.185 mol
CaCO3, or calcium carbonate, has a molar mass of 100.09 grams per mole. This means there are roughly 566 grams of CaCO3.
3,56 mol Al is equal to 96,05 grams.
SrCl2 Strontium (Sr) = 87.62 grams/mol 2 Chlorine (Cl) = 70.9 grams/mol ----------------------------------------------------add Strontium chloride = 158.52 grams/mol ============================
1.9 mol Se ( 78.96 grams/1mol Se ) = 150.024 grams
1.3 mole C2H2 will produce 2.6 mole CO2, weighting 2.6(mol) x 44 (g/mol) = 114 g CO2
the mass of carbon-12 atom in mole is 12 only...
The mass in grams of 5,01 mol of xenon is 657,778 g.
12
1 mole of carbon is 12.0107 grams Multiply by 5 and you get 60.0535 grams
5 M NaOH = 5 mol/L NaOH. 1 mol of NaOH = 40 g NaOH. You can get the number of grams by multiplying 5 mol/L and 40g/mol. This will give you 200g/L. Just multiply by the volume, which is 1 Liter, and you will get 200 g of NaOH.
