Please see below solution:
1 lb Hg x (151.50/76 lb) = cost of 1 lb.
<span>cost 1 lb x (1g/453.6 g) = cost of 1 g.</span>
Answer:
there are 6.022*1023 atoms
Explanation:
32 g S * (1 mole S/32 g S) * (6.022*1023 atoms/1 mole S)= 6.022*1023 atoms
Answer:


Explanation:
Hello there!
In this case, according to the described chemical reaction, it is possible to compute the theoretical mass of silver as mass via the 1:2 mole ratio of copper to silver and their atomic mass in the periodic table, in order to perform the following stoichiometric setup:

Next, given the actual yield of 120 g, we compute the percent yield via:
