Molar mass of empirical formula = 172.8 g/mole
346.6g/172.8 g/mole = 2.00 moles
Molecular formula = C2H2Br4
Answer:
Explanation:
A single electron has a charge of 1.60217733 × 10-19 Coulombs. A collection of 6.2415 × 1018 electrons has a charge of one Coulomb (1/1.60217733x10-19). 1.6 into 10 raise to power -19 no of electrons are present in one coulomb of charge.
To get the least degree of precision I would model it after the kg amount or 4.05 or two decimal places so I would add 0.56795 or to two places would be 0.57 kg and then 0.1001 kg would be 0.1 kg so my answer would be 4.72 kg. In contrast, the greatest degree of precision would be 4050g + 567.95 grams plus 100.1 g= 4718.05 grams or 4.71805 kg. At least that is what I would think..
