Correct Option - 3

Detailed Solution:

t = 0 $\frac{20}{28}$ $\frac{5}{2}$ 0

Here, N₂ is the limiting reagent

and No of moles of NH₃ = 2 × No of moles ofN₂ reacted

$2 \times \frac{20}{28} = \frac{40}{28} = \frac{1.42}{}$

$C H_{4} + 2 O_{2} \to C O_{2} + 2 H_{2} O$

Mole $\frac{100}{16} \frac{208}{32}$

$\begin{array}{l} ↓ ↓ \\ 6.25 6.5 (H e r e O_{2} i s t h e l i m i t i n g r e a g e n t) \end{array}$

Hence mole of CO₂ formed = $\frac{6.5}{2}$

And wt of CO₂ in gm = $\frac{6.5}{2} \times 44 = 143 g$

The number of radial land angular nodes in 4d orbital are, respectively

Vishal Baghel

In 4d orbital, n = 4 and $l = 2$

Radial nodes = $n - l - 1$

Radial nodes = 4 – 2 – 1 = 1

And angular nodes, $l = 2$

$M o l a l i t y = \frac{m o l e s o f s o l u t e \times 1000}{w t o f s o l v e n t (g m)}$

$M o l a l i t y = \frac{35 \times 1000 \times 1.46}{36.5 \times 100}$ = 14.0 M

Chlorophyll extracted form the crushed green leaves was dissolved in water to make 2 L solution of Mg of concentration 48 ppm. The number of atoms of Mg in this solution is x × 10²⁰ atoms. The value of x is _____________. (Nearest Integer)

(Given : Atomic mass of Mg is 24 g mol^-1; N_A = 6.02 × 10²³ mol^-1)

Vishal Baghel

Mass of solute = 48 * 2 * 10^-3 gram

Atoms of Mg = 24.08 * 10²⁰

A sample of 0.125g of an organic compound when analyzed by Duma’s method yields 22.78 mL of nitrogen gas collected over KOH solution at 280 K and 759 mm Hg. The percentage of nitrogen in the given organic compound is__________. (Nearest integer)

[Given: (a) The vapour pressure of water of 280K is 14.2mm Hg

(b) R = 0.082 L atm K^-1 mol^-1]

Vishal Baghel

$V_{N_{2}} = 22.78 m l T = 280 K$

PTotal = 759 mm of Hg

$P_{N_{2}} = 759 - 14.2 = 744.8 m m H g$

$n_{N_{2}} = \frac{744.8 \times (22.78 / 1000)}{(0.082 \times 760) \times 280}$

= 0.00097

$% N = \frac{0.02716}{0.125} \times 100 = 21.728$

$\approx 22 .$
