Answer:
11.74
Explanation:
The formula to find the pH of a solution is..
pH = -log [H⁺]
pH = -log [1.8×10¹²]
pH = 11.74
The answer would be to 2 decimal places because the concentration is two significant digits.
Answer:
Explanation:
<u>Given:</u>
Density = ρ = 0.8 g/cm³
Volume = V = 225 cm³
<u>Required:</u>
Mass = m = ?
<u>Formula:</u>
m = ρV
<u>Solution:</u>
m = (0.8)(225)
m = 180 g
![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
