  • 2moles of NaCl produced by 2 moles of NaClO_3
  • Let required moles be x .

\\ \bull\sf\longmapsto 2:2=3:x

\\ \bull\sf\longmapsto \dfrac{2}{2}=\dfrac{3}{x}

\\ \bull\sf\longmapsto \dfrac{3}{x}=1

\\ \bull\sf\longmapsto x=3mol

Answer:

• From the equation

{ \rm{2 \: moles \: of \: chlorate = 2 \: moles \: of \: chloride}} \\ { \rm{3 \: moles \: of \: chlorate = ( \frac{3}{2}  \times 2)}} \\  \\  = { \boxed{ \rm{3 \: moles}}}

A circle is inscribed in a square with a side length of 144. If a point in the square is chosen at random, what is the probabili
____ [38]

Given :

A circle is inscribed in a square with a side length of 144.

So, radius of circle, r = 144/2 = 72 units.

To Find :

The probability that the point is inside the circle.

Solution :

Area of circle,

A_c = \pi r^2\\\\A_c = 3.14 \times 72^2\ units^2\\\\A_c = 16277.76 \ units^2

Area of square,

A_s = (2r)^2\\\\A_s = ( 2 \times 72)^2\ units^2\\\\A_s = 20736\ units^2

Now, probability is given by :

P = \dfrac{A_c}{A_s}\\\\P = \dfrac{16277.76}{20736}\\\\P = 0.785

Therefore, the probability that the point is inside the circle is 0.785 .
