Answer:
d = 0.93 g/cm³
Explanation:
Given data:
Mass of object = 28 g
Volume of object = 3cm×2cm×5cm
density of object = ?
Solution:
Volume of object = 3cm × 2cm ×5cm
Volume of object = 30 cm³
Density of object:
d = m/v
by putting values,
d = 28 g/ 30 cm³
d = 0.93 g/cm³
Answer:
None
Step-by-step explanation:
A high pH is caused by an excess of hydrogen ions over hydroxide ions.
Hydrogen ions are so small that they pass through the pores of an ordinary filter.
Thus, ordinary filtration has no effect on the pH of water.
