Never mind, I did the problem wrong, I deeply apologize.
ANSWER: B salt does not evaporate with water
Answer:
![\large \boxed{\text{110 mmHg}}}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7B%5Ctext%7B110%20mmHg%7D%7D%7D)
Explanation:
We can use Dalton's Law of Partial Pressures:
Each gas in a mixture of gases exerts its pressure separately from the other gases.
In other words, if a gas makes up 3.0 % of the atmosphere, its partial pressure is 3.0 % of the total pressure.
![p_{\text{N}_{2}} = p_{\text{tot}} \times \dfrac{\text{3.0 parts N}_{2}}{\text{100 parts atmosphere}}= \text{3700 mmHg} \times \dfrac{\text{3.0 mmHg}}{\text{100 mmHg}} = \textbf{110 mmHg}\\\\p_{\text{N}_{2}} = \large \boxed{\textbf{110 mmHg}}](https://tex.z-dn.net/?f=p_%7B%5Ctext%7BN%7D_%7B2%7D%7D%20%3D%20p_%7B%5Ctext%7Btot%7D%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B3.0%20parts%20N%7D_%7B2%7D%7D%7B%5Ctext%7B100%20parts%20atmosphere%7D%7D%3D%20%5Ctext%7B3700%20mmHg%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B3.0%20mmHg%7D%7D%7B%5Ctext%7B100%20mmHg%7D%7D%20%3D%20%5Ctextbf%7B110%20mmHg%7D%5C%5C%5C%5Cp_%7B%5Ctext%7BN%7D_%7B2%7D%7D%20%3D%20%5Clarge%20%5Cboxed%7B%5Ctextbf%7B110%20mmHg%7D%7D)
Bike is B
Horn is H
Tire is T
Chain is C
one bike would be B = H + 2T + C
you would have to multiply both sides by 4 to make 4 bikes, so then it would be
4B = 4H + 8T + 4C
