Answer:
The answer to your question is 5.74 g of Silver
Explanation:
Data
number of atoms = 3.20 x 10²²
mass of silver = ?
Process
The atomic number of an element is equal to Avogadro's number (6.023 x 10²³).
1.- Look for the atomic number of Silver
Atomic number = 108 g
2.- Use proportions to calculate the grams of silver
108 g of Silver ----------------- 6.023 x 10²³ atoms
x ------------------ 3.20 x 10²² atoms
x = (3.20 x 10²² x 108) / 6.023 x 10²³
x = 3.456 x 10²⁴/ 6.023 x 10²³
x = 5.74 g of Silver
Answer:
the particels becomes loose and wild, making gas happen when it is heated up
The statement that best describes waves is B. Waves cannot propagate without a medium
Largest to smallest: barium, calcium, selenium, oxygen
1. So 27.3 g Fe is 0.4911 mol (27.3 / 55.58). 45.8 g O is 2.862 mol. Because of the stoichiometry, 3/4 as much oxygen as iron gets consumed. For the 0.4911 mol Fe consumed, 0.3683 mol O is consumed. 2.862-0.3863 = 2.4757 mol, or 39.6 g O is left.
2. Hydrogen is the limiting reactant for these quantities. 2/3 as much ammonia is produced as hydrogen is consumed, so for 5.0 mol H2, that's 3.33 mol NH3.
Make sense?
