How many atoms of sulfur are present in 155 g of sulfur?

Answer 1

The Atomic Mass of sulfur is 32. A mole of sulfur, or 32 grams, contains 6.02 x 1023 atoms (Avogadro's Number). 155 grams must contain 155/32 times that many atoms, or 2.9 x 1024 atoms.

Answer 2

To determine the number of sulfur atoms in 155 g of sulfur, you first need to calculate the number of moles of sulfur present. The molar mass of sulfur is approximately 32.06 g/mol. By dividing the given mass by the molar mass, you find that there are approximately 4.83 moles of sulfur. Since one mole of sulfur contains Avogadro's number of atoms (6.022 x 10^23), you can calculate that there are approximately 2.91 x 10^24 sulfur atoms in 155 g of sulfur.

Answer 3

93,341,000,000,000,000,000,000,000 or 933.41 x 1023 atoms of arsenic. You just take Avogadro's number (6.022 x 1023) and multiply 6.022 by the number of moles (155) and then multiply the product by 1023.

Answer 4

To find the number of atoms in 155 g of sulfur, you first need to determine the number of moles of sulfur in 155 g using the molar mass of sulfur (32.06 g/mol). Then use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
