Answer:
<u>The pH at equivalence is 5.24 .</u>
Explanation:
Let us calculate -
millimoles of aniline = 160 x 0.3403 = 54.448
To reach equivalence , 54.448 millimoles HNO3 must be added,
V = 1086.79 mL HNO3 must be added
total volume = 1086.79 + 160 = 1246.79 mL
Concentration of [salt] = = 0.044 M
Now, at the equivalence or equivalent point ,
By solving the above equation , we get -
pH = 5.24
<u>Hence , the answer is 5.24 </u>

Explanation:
Hello,
In this case, given that 1 inch equals 2.54 cm and 1 lb equals 453.6 g we apply the following conversion factor in order to compute the required density in lb/in³:

Answer:
Mass of solid = 189.141 gram
Explanation:
Given:
Total volume = 93 ml
Mass of liquid = 33.7 gram
Density of liquid = 0.865 g/ml
Density of solid = 3.50 g/ml
Find:
Mass of solid = ?
Computation:
Volume of liquid = Mass of liquid / Density of liquid
Volume of liquid = 33.7 / 0.865
Volume of liquid = 38.9595 ml
Volume of solid = Total volume - Volume of liquid
Volume of solid = 93 - 38.9595
Volume of solid = 54.0405 ml
Mass of solid = Volume of solid × Density of solid
Mass of solid = 54.0405 ml × 3.50 g/ml
Mass of solid = 189.141 gram
