Answer: Vinegar
Explanation:
The vinegar and salt affects the shell because food coloring does not affect anything besides the color so the viniger has substances which dissolves thing and the salt just made the vinegar a stronger substance. The Vinegar reactes to form a compund on the shell.
For the purpose we will here use t<span>he ideal gas law:
p</span>×V=n×R×<span>T
V= </span><span>5.0 L
T= </span><span>373K
p= </span><span>203kPa
</span><span>
R is </span> universal gas constant, and its value is 8.314 J/mol×<span>K
</span>
Now when we have all necessary date we can calculate the number of moles:
n=p×V/R×T
n= 203 x 5 / 8.314 x 373 = 0.33 mole
Take the 72 g and divid it by 6 which would equal 12 g each
