Batrachospermum Occurrence:- (1) Batrachospermum is fresh water alga. (2) It is found in clear, cool, and running streams. (3) Deepwater plants are dark violet or reddish in color. But the shallow-water species are olive green. (4) The intensity of light changes the color of pigments. (5) The thallus is attached to the substratum. Vegetative structure (1) The thallus of an adult plant is soft, thick, filamentous. (2) It is freely branched and gelatinous. (3) The central axis is made up of a single row of large cells. Whorls of branches of limited growth are developed on this axis. (4) These branches are filamentous and dichotomously arranged. (5) The main axis is corticated. It consists of a row of elongated cylindrical cells. (6) It is differentiated into nodes and internodes. (7) There are two types of branches that arise from the nodes: Branches of limited growth Branches of unlimited growth Batra
Chemistry Chapter -Solution Part-2 How do you find the molar mass of Colligative properties? How do you find the molar mass of a solute? How do you determine Colligative properties? How do you find the molecular weight of an unknown compound? Topics to be covered in this Post Molality Molarity Normality Mole fraction Colligative properties Molality:- It is defined as the total moles of solute dissolved in the weight of the solvent . Molality = Number of moles of solute/weight of solvent in (k.g.) It is denoted by "m" Its unit is moles/kg. Molarity:- It is defined as total number of moles of solute dissolved in the volume of the solution. Molarity = Number of moles of solute/volume of solution(ltr) It is denoted by "M" its unit is moles/ltr Normality = It is defined as the number o
