just checked on edg
Answer:
Actual yield: 86.5 grams.
Explanation:
How many moles of formula units in 95 grams of calcium carbonate
?
Refer to a modern periodic table for relative atomic mass data:
- Ca: 40.078;
- C: 12.011;
- O: 15.999.
Formula mass of
:
.
.
How many moles of
will be produced?
The coefficient in front of
in the chemical equation is the same as that in front of
. That is:
.
.
What's the theoretical yield of calcium chloride? In other words, what's the mass of
of
?
Again, refer to a periodic table for relative atomic data:
.
.
What's the actual yield of calcium chloride?
.
.
