Lubos na paumanhin. maaari mo bang ipaliwanag muli ang tanong? sa totoo lang galing ako sa phillipines, masasabi mo ba sa fillipino; wika ko
Sorry I honestly have no idea I just want my points
The answer is 4.
Gases have low densities, because of the increased space between hight-energy particles.
Given that 1 mole contains 6.02x10^23 molecules, 3.0x10^23 is just around half a mole. Then we check the number of moles for each choice:
A. This is approximately half a mole, since the molar mass of Br2 is 159.8 g/mol.
B. He has a molar mass around 4 g/mol, so this is 1 mole.
C. H2 has a molar mass of 2.02 g/mol, so this is 2 moles.
D. Li has a molar mass of around 6.97 g/mol, so this is around 2 moles.
Therefore the only choice that fits is A. 80 g of Br2.
