Hey there !
Molar mass HCl :
HCl =1.01 + 35.45 => 36.46 g/mol
Number of moles ( solute) :
n = m / mm
n = 9.63 / 36.46
n = 0.2641 moles
Therefore :
M = moles / volume ( L )
M = 0.2641 / 1.5
=> 0.176 M
Answer:
B
Explanation:
Temperature & pressure are directly proportional
Answer:
0.015 M HNO3 = 0.015 M H3O+ pH = -log(0.015) = 1.82 [OH -] = 1.0 x 10 -14/0.015 M = 6.7 x 10 13 Check: HNO3 is a strong acid, so we expect the pH to be low and the [OH ] to be small
The answer to your question is A
