D is the correct answer for your question. Maybe I am not sure.
Answer:
The answer is below
Explanation:
The density of an object is its mass per unit of volume. Dense objects feel very heavy for their size, while for objects with low density they are very light for their size.
Density is the ratio of mass to volume; it is given by:
Density (D) = mass (m) / volume (V)
An object sinks in water if the density of the object is greater than the density of water. While an objects floats on water if the density of the object is les than the density of water
Answer:
The answer to your question is 308.1 g of KmNO₄
Explanation:
Data
Volume = 6 L
Concentration = 0.325 M
Molar mass of Potassium permanganate = 39 + 55 + (16 x 4) = 158 g
Process
1.- Calculate the moles of KMnO₄
Formula
Molarity = moles/volume
moles = molarity x volume
moles = 0.325 x 6
moles = 1.95
2.- Calculate the grams of KMnO₄
158 g KMnO₄ ------------------ 1 mol
x ------------------ 1.95
x = (1.95 x 158)/1
x = 308.1 g
