Answer:
66 grams of carbon dioxide
C3H8+5O2=3CO2+4H2O
Answer:- 60860 mg of Ba.
Solution:- Concentration of barium nitrate solution is given as 61.2 grams per liter. It asks to calculate the mg of Barium in 2 quarts of the solution.
quart is the unit of volume. Since the concentration is given in grams per liter. Let's convert quarts to liters. The important conversion factors are:
1 gallon = 4 quarts
1 gallon = 3.785 liters
So, from these two conversion factors, 4 quarts = 3.785 liters
= 1.8925 L
Let's calculate grams of barium nitrate present in these 1.8925 liters as:
=
Molar mass of barium nitrate = 137.33 + 2(14) + 6(16)
= 137.33 + 28 + 96
= 261.33 gram per mol
There is one Ba present in barium nitrate, So, we could say that 261.33 g of barium nitrate has 137.33 g of Ba. How many grams of Ba would be present in 115.821 g of barium nitrate. let's make the set up as:
= 60.86 g Ba
It want's answer in mg. So, let's convert g to mg.
1 g = 1000 mg
So,
= 60860 mg of Ba
So, 60860 mg of Ba are present in 2 quarts of the barium nitrate solution.

The difference between relative abundance and percent abundance is that relative abundance refers relatively to the number of items you used in the experiment, where as the Percent abundance is referring to how many of each items there are in every hundred items.
Percent abundance is how abundant an isotope is in nature or the universe; it is how common or rare an isotope is. I hope this made sense.
