The molarity of the HCl is 1 M when 12.0 of .500 M NaOH neutralized 6.0 ml of HCl solution.
Explanation:
Data given:
molarity of the base NaOH, Mbase =0. 5 M
volume of the base NaOH, Vbase = 12 ml
volume of the acid, Vacid = 6 ml
molarity of the acid, Macid = ?
The titration formula for acid and base is given as:
Mbase Vbase = Macid Vacid
Macid =
Macid = 1 M
we can see that 1 M solution of HCl was used to neutralize the basic solution of NaOH. The volume of NaOH is 12 ml and volume of HCl used is 6ml.

Un enlace químico es una atracción duradera entre átomos, iones o moléculas que permite la formación de compuestos químicos.
Explanation:
Answer:
2.13atm
Explanation:
The following information were obtained from the question:
P1 (initial pressure) = 2atm
T1 (initial temperature) = 27°C = 27 + 273 = 300K
T2 (final temperature) = 47°C = 47 + 273 = 320K
P2 (final pressure) =?
Using the equation P1/T1 = P2/T2, the final pressure within the tyre can be obtained as illustrated below:
P1/T1 = P2/T2
2/300 = P2/320
Cross multiply to express in linear form
300 x P2 = 2 x 320
Divide both side by 300
P2 = (2 x 320)/300
P2 = 2.13atm
Therefore, the pressure within the tyre at 47°C is 2.13atm
