0.70 g of hydrogen chloride (HCl) is dissolved in water to make 5.0 L of solution. What is the pH of the resulting hydrochloric acid solution? Express the pH numerically to two decimal places.

( About ) 2.42 pH

Explanation:

First convert grams to mole of the hydrochloric acid,

HCl ( moles ) = 0.7g * ( 1 mole / 36.5g ),

0.7 / 36.5 = ( About ) 0.0192 moles

Now take the moles as a fraction over the given liters, to determine " M, " the apparent pH

M = 0.0192 mole / 5.0 L,

M = 0.00384M

Because HCl is a strong acid and will completely ionized, take a look at the steps below,

[ H+ ] = 0.00384M pH = -log[H+] = - log[0.00384],

- log[0.00384] = - ( - 2.41566... )

Solution = ( About ) 2.42 pH

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

you gotta add the following molecules so we can give u an answer
