Weight of D-glucose in water =\( 250\) \(g\)
∴ Weight of carbon in D-glucose
= \(\frac{250}{180}×72 = 100\) \(g\)
Percentage of carbon in the aqueous solution of glucose is
= \(10.8\%\)
∴ Weight of the solution is = \(925.93\)
∴ Molality of D-glucose is
=\(\frac{\frac{ 250}{180}}{(925.93 - 250)}×1000\)
= \(\frac{250}{180×675.93} ×1000\)
= \(2.06\)
Hence, the correct option is (B): \(2.06\)
Let \( y = f(x) \) be the solution of the differential equation
\[ \frac{dy}{dx} + 3y \tan^2 x + 3y = \sec^2 x \]
such that \( f(0) = \frac{e^3}{3} + 1 \), then \( f\left( \frac{\pi}{4} \right) \) is equal to:
Find the IUPAC name of the compound.
If \( \lim_{x \to 0} \left( \frac{\tan x}{x} \right)^{\frac{1}{x^2}} = p \), then \( 96 \ln p \) is: 32
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
For example, salt and sugar is a good illustration of a solution. A solution can be categorized into several components.
The solutions can be classified into three types:
On the basis of the amount of solute dissolved in a solvent, solutions are divided into the following types:
