Answer:
B. Lower
Explanation:
Remember that the pH is calculated as
-log (H30 +)
That is, at a higher concentration of H30 +, with the -log, the pH value decreases and vice versa.
With a concentration 1e-5, it yields a pH of 5.00 and with 1e-2 a value of 2.00
Use equation density = mass/volume
Known/Given
d= 10.5g/cm^3
v= 24.0 cm^3
Use that equation i just mentioned...
Solution
Rewrite the formula as the forumla for solving density into mass
Which is... mass = 10.5g/cm^3 × 24.0cm^3 = 252g
So thats the answer
252g
Hope i could help
