Mass of 1 mole of AL2(SO4)3 =340g
By unitary method, we get 340g=1 mole
12g= 12/340 moles
1 mole contains 6.022*1023 atoms
12/340 moles contain 12/340*6.022*1023 atoms=21.25*1021 atoms.
1 mole is equal to 18 grams of H2O, so 60 grams is 3.33 moles.
The molar mass of gold is approximately 197 grams/mol. To convert moles to grams, you multiply the number of moles by the molar mass. Therefore, 2.8 moles of gold would be approximately 2.8 * 197 = 551.6 grams.
0.1538 grams
To find the number of moles in 57 grams of Xenon, divide the given mass (in grams) by the molar mass of Xenon. The molar mass of Xenon is 131.3 grams/mol. Therefore, 57 grams of Xenon is equal to 0.434 moles (57/131.3).
To convert moles to grams, you need to use the molar mass of Xenon, which is 131.3 g/mol. Multiplying 44.3 moles by the molar mass gives you a total of 5812.59 grams of Xenon.
