How many atoms are there in 61.7 g of selenium?
1 mol of sulfur contains 6.02 x 1023 molecules (avogadro constant). In one molecule of sulfur, S8, there are 8 sulfur atoms. Thus, number of atooms in 7.20 moles of sulfur = 8 x 7.20 x 6.02 x 1023 = 3.47 x 1025 Note: Sulfur does not usually exist in a monatomic form but instead forms cyclic octatomic molecules with molecular formula S8.
Determine the mass in grams of 5.56x1024 atoms of selenium?
To determine the mass, you need to first find the molar mass of selenium, which is 78.971 g/mol. Then, divide the number of atoms by Avogadro's number to find the number of moles (5.56x10^24 atoms / 6.022x10^23 atoms/mol). Finally, multiply the number of moles by the molar mass to get the mass in grams (moles x molar mass).
What is the molarity of a 5ml solution containing 0.7 micrograms of selenium?

How do you convert 2.76 g SE to moles SE?
To convert grams of selenium (Se) to moles, divide the given mass by the molar mass of selenium. The molar mass of selenium is approximately 78.97 g/mol. ( \dfrac{2.76 : g}{78.97 : g/mol} = 0.035 : mol : Se)
