I took the mg and converted it to grams. That gave me .325 grams. I took that and multiplied that by 3628 grams. If I did my math correctly, the answer would be 1179.1. Rounded up, that would be 1179 aspirin tablets.
Hope this helps. :)
C. Temperature. The greater the temperature of a substance the greater the average kinetic energy of the particles that made up the substance.
Answer:
The answer is
<h2>32 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 40 mL
density = 0.80 g/mL
The mass is
mass = 40 × 0.8
We have the final answer as
<h3>32 g</h3>
Hope this helps you
Answer:
![[I_2]=[Br]=0.31M](https://tex.z-dn.net/?f=%5BI_2%5D%3D%5BBr%5D%3D0.31M)
Explanation:
Hello there!
In this case, according to the given information, it is possible for us to set up the following chemical equation at equilibrium:
Now, we can set up the equilibrium expression in terms of x (reaction extent) whereas the initial concentration of both iodine and bromine is 0.5mol/0.250L=2.0M:
![K=\frac{[IBr]^2}{[I_2][Br_2]} \\\\1.2x10^2=\frac{(2x)^2}{(2.0-x)^2}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BIBr%5D%5E2%7D%7B%5BI_2%5D%5BBr_2%5D%7D%20%5C%5C%5C%5C1.2x10%5E2%3D%5Cfrac%7B%282x%29%5E2%7D%7B%282.0-x%29%5E2%7D)
Thus, we solve for x as show below:
Therefore, the concentrations of both bromine and iodine are:
![[I_2]=[Br]=2.0M-1.69M=0.31M](https://tex.z-dn.net/?f=%5BI_2%5D%3D%5BBr%5D%3D2.0M-1.69M%3D0.31M)

No! If it was 12% a 150 pound person would be about 18 pounds of salt!
~0.4%
The average 150lb person would contain ~280 g of NaCl.
