Answer:
c. 3.3
Step-by-step explanation:
edg
pH = 3.3
pH is given by the formula; pH = –log[H+]
The concentration of hydrogen ions is 5.0 × 10–4 moles per liter.
Therefore;
pH = - log₁₀(5.0 × 10^–4)
= -( - 3.301)
= 3.301
Thus;
The approximate pH will be; 3.3
the answer is $2310
x=1 y=2.5
x=8
Those angles are supplementary so:
140+5x=180
5x=40
