The density of lithium cylinder of height 1.2 mm and diameter 15 cm with mass 0.3624 g is to be reported. Concept introduction: The density of any object is obtained when the mass of object in grams is divided by volume of an object in milliliters. So it is denoted by unit: gram per milliliter. Density is directly associated to the mass of an object. The higher the mass of the substance higher will be its density. Density is inversely associated to the volume of a substance. The lower the volume of the substance higher will be its density. Density is associated to how the particles are packed in a substance, which in turn determines its state. The state of a substance defines density. Solids are characterized by the highest and gases by the least density.

Concept introduction:
The density of any object is obtained when the mass of object in grams is divided by volume of an object in milliliters. So it is denoted by unit: gram per milliliter.
Density is directly associated to the mass of an object. The higher the mass of the substance higher will be its density. Density is inversely associated to the volume of a substance. The lower the volume of the substance higher will be its density.
Density is associated to how the particles are packed in a substance, which in turn determines its state. The state of a substance defines density. Solids are characterized by the highest and gases by the least density.
A 0.10 M solution of acetic acid (CH3COOH, Ka = 1.8 x 10^-5) is titrated with a 0.0250 M solution of magnesium hydroxide (Mg(OH)2). If 10.0 mL of the acid solution is titrated with 20.0 mL of the base solution, what is the pH of the resulting solution?
For the decomposition reaction of N2O5(g): 2 N2O5(g) → 4 NO2(g) + O2(g), the following mechanism has been proposed:
N2O5 NO2 + NO3 (K1) | NO2 + NO3 → N2O5 (k-1) | NO2 + NO3 NO2 + O2 + NO (k2) | NO + N2O51 NO2 + NO2 + NO2 (K3)

Do not apply the calculations, based on the approximation of the stationary state, to make them perform correctly. Basta discard
the 3 responses that you encounter that are obviously erroneous if you apply the formula to determine the speed of a reaction.
