In Carius method of estimation of halogen, 0.45 g of an organic compound gave 0.36 g of AgBr. Find out the percentage of bromine in the compound.
(Molar masses: AgBr = 188 g mol–1; Br = 80 g mol–1)
(Molar masses: AgBr = 188 g mol–1; Br = 80 g mol–1)
- 34.04%
- 40.04%
- 36.03%
- 38.04%
The Correct Option is A
Solution and Explanation
The correct answer is (A):
188g of AgBr = 80g of Br
0.36g of AgBr = \(\frac{80}{188}\)×0.36
Percentage of Br in given organic compound
= 80×\(\frac{0.36}{188}\)×0.45×100
= 34.04%

Types of Differential Equations
There are various types of Differential Equation, such as:
Ordinary Differential Equations:
Ordinary Differential Equations is an equation that indicates the relation of having one independent variable x, and one dependent variable y, along with some of its other derivatives.
\(F(\frac{dy}{dt},y,t) = 0\)
Partial Differential Equations:
A partial differential equation is a type, in which the equation carries many unknown variables with their partial derivatives.
Linear Differential Equations:
It is the linear polynomial equation in which derivatives of different variables exist. Linear Partial Differential Equation derivatives are partial and function is dependent on the variable.
Homogeneous Differential Equations:
When the degree of f(x,y) and g(x,y) is the same, it is known to be a homogeneous differential equation.
\(\frac{dy}{dx} = \frac{a_1x + b_1y + c_1}{a_2x + b_2y + c_2}\)
