I m having a lot of trouble solving these problems.
1. How many individual silver atoms are found in 3.5 x 1023 gold atoms?
2. How many grams of silver are found in 4.8 moles silver? (108 gram silver = 1mol silver)
3. How many moles of silver are found in 10 grams silver?
Chem Homework Help? Really stuck on this?

✔ 最佳答案
1.No silver atom can be found in gold atoms.
Number of individual silver atoms in 3.5 × 10²³ gold atoms = 0 atom
2.
Mass of silver = (108 g/mol) × (4.8 mol) = 520 g (to 2 sig. fig.)
3.
Number of moles of silver = (10 g) / (108 g/mol) = 0.093 mol (to 2 sig. fig.)
