1 answer:
Answer:
<h2>Density = 41.8 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
<h3>From the question
mass = 498 g
volume = 11.9 mL
Substitute the values into the above formula and solve for the Density
That's
<h3>We have the final answer as
<h3>Density = 41.8 g/mL</h3>Hope this helps you

Answer:
The answer to your question is P = 1.357 atm
Explanation:
Data
Volume = 22.4 L
1 mol
temperature = 100°C
a = 0.211 L² atm
b = 0.0171 L/mol
R = 0.082 atmL/mol°K
Convert temperature to °K
Temperature = 100 + 273
= 373°K
Formula
Substitution
Simplify
(P + 0.0094)(22.3829) = 30.586
Solve for P
P + 0.0094 =
P + 0.0094 = 1.366
P = 1.336 - 0.0094
P = 1.357 atm
1 tablespoon = 0.5 ounces
We are required to find for 2 table spoons.
2 table spoons = 2 x 0.5 = 1 ounce.
Each bottle has 16 ounce.
Number of bottles = 4
So total number = 4 x 16 = 64 ounces.
Number of 2 table spoons =
= 64
Thus there are 64 2-tablespoon doses are in 4 bottles of medication containing 16 ounces each.
