The gram atomic/molar mass of cobalt is 63.546. Multiplying this number by 0.0489 yields the answer of 3.11 grams, to the justified number of significant digits.
1 mole Co = 58.933200g Co
0.0489mol Co x 58.933200g/mol = 2.88g Co
To get the mass in grams of 0.0483 mol of iron you need to get its volume as well.
mol = mass/Mr mol x Mr = mass Mr of tungsten is 183.84 so 1.2 x 183.84 = 220.61g
The mass in grams of 1,40 mol of anhydrous iron(III) sulfate is 559,832.
0.330 moles of calcium has a mass of 13.2 grams.

1 mol = 197g therefore, 32 mol = 6306 grams
The mass in grams of 5,01 mol of xenon is 657,778 g.
mol = mass/Mr mol x Mr = mass Mr of tungsten is 183.84 so 1.2 x 183.84 = 220.61g
1.9 mol Se ( 78.96 grams/1mol Se ) = 150.024 grams
The mass in grams of 1,40 mol of anhydrous iron(III) sulfate is 559,832.
0.330 moles of calcium has a mass of 13.2 grams.
Carbon tetraflouride or CF4, has a molar mass of 88.004 grams per mol. 1.32 mols of CF4 then has a mass of 116 grams
The mass of 2.000 mol of oxygen atoms is 32.00 grams.

The answer is 399 grams
The answer is 69.7247149193
The answer is 319,15 g.
Mole / Molar mass = mass = 0.118 [mol] /169.87 [g mol−1] = 20.05 grams
