A compound has a pH of 3 what is the [H+] concentration?

Chemistry
1 answer:
Allisa [31]3 years ago
8 0

Answer: 0.001 M

Explanation:

pH is the negative logarithm of hydrogen ion concentration in a solution. Mathematically, pH is expressed as

pH = -log(H+)

where H+ is hydrogen ion concentration

So, 3 = -log(H+)

(H+) = Antilog (-3)

(H+) = 0.001

Thus, [H+] concentration is 0.001 M

#2: A gas at unknown pressure and a volume of 66 cm has its pressure changed to 150 kPa. The new volume
Murljashka [212]

Answer:

<h2>377 kPa</h2>

Explanation:

The original pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the original pressure

P_1 =  \frac{P_2V_2}{V_1}  \\

150 kPa = 150,000 Pa

We have

P_1 =  \frac{150000 \times 166}{66}  =  \frac{24900000}{66}  \\  = 377272.72...

We have the final answer as

<h3>377 kPa</h3>

Hope this helps you
