Answer:
![\Delta \rho =2.22 g/mL](https://tex.z-dn.net/?f=%5CDelta%20%5Crho%20%3D2.22%20g%2FmL)
Explanation:
Hello,
In this case, since a change in science is widely known to be considered as a subtraction between the the final and initial values of two measured variables and is represented via Δ, here the final density is 5.43 g/mL and the initial one was 3.21 g/mL, therefore, the change in density is:
![\Delta \rho=\rho _f-\rho _i\\ \\\Delta \rho=5.43g/mL-3.21g/mL\\\\\Delta \rho =2.22 g/mL](https://tex.z-dn.net/?f=%5CDelta%20%5Crho%3D%5Crho%20_f-%5Crho%20_i%5C%5C%20%5C%5C%5CDelta%20%5Crho%3D5.43g%2FmL-3.21g%2FmL%5C%5C%5C%5C%5CDelta%20%5Crho%20%3D2.22%20g%2FmL)
Best regards.
30.07 g/mol (that’s grams per mole)
Step one: Identify reactants and products and place them in a word equation.
Step two: Convert the chemical names into chemical formulas. Place them based on the chemical equation and write the state symbols.
Step three: balance the chemical equation.
Answer:
The ration of molar concentration is "2.5".
Explanation:
The given values are:
Average density of salt water,
= ![1.03 \ g/cm^3](https://tex.z-dn.net/?f=1.03%20%5C%20g%2Fcm%5E3)
Net pressure,
= ![2.00 \ atm](https://tex.z-dn.net/?f=2.00%20%5C%20atm)
Increase in pressure,
= ![1.00 \ atm](https://tex.z-dn.net/?f=1.00%20%5C%20atm)
Now,
The under water pressure will be:
= ![\frac{15 \ m}{10}\times 1 \ atm +1 \ atm](https://tex.z-dn.net/?f=%5Cfrac%7B15%20%5C%20m%7D%7B10%7D%5Ctimes%201%20%5C%20atm%20%2B1%20%5C%20atm)
= ![1.5\times 1+1](https://tex.z-dn.net/?f=1.5%5Ctimes%201%2B1)
= ![1.5+1](https://tex.z-dn.net/?f=1.5%2B1)
= ![2.5 \ atm](https://tex.z-dn.net/?f=2.5%20%5C%20atm)
hence,
The ratio will be:
= ![\frac{(\frac{n}{V})_{15m} }{(\frac{n}{V})_{surface} }](https://tex.z-dn.net/?f=%5Cfrac%7B%28%5Cfrac%7Bn%7D%7BV%7D%29_%7B15m%7D%20%7D%7B%28%5Cfrac%7Bn%7D%7BV%7D%29_%7Bsurface%7D%20%7D)
or,
= ![\frac{P}{P_s}](https://tex.z-dn.net/?f=%5Cfrac%7BP%7D%7BP_s%7D)
= ![\frac{2.5}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B2.5%7D%7B1%7D)
= ![2.5](https://tex.z-dn.net/?f=2.5)
