Answer:

The atomic weight (or atomic mass) of Vanadium is 50.9415 which means that a "mole" of Vanadium atoms (6.02 x 10^23 atoms) will have a mass of 50.9415 grams. So, 214.1 grams of Vanadium would have

(214.1 / 50.9415) * (6.02 x 10^23) = 2.530 x 10^24 atoms

I. The value of x is equal to 8.

II. The dimensions of the rectangle are 13 and 5 inches respectively.

Given the following data:

Area of a rectangle = 65 square inches.

Length of rectangle = x + 5 inches

Width of rectangle = x - 3 inches

To find the value of x, and the dimensions of the rectangle:

Mathematically, the area of a rectangle is given by the formula:

$A = LW$

Substituting the values, we have:

$65 = (x+5)(x-3)\\\\65=x^2-3x+5x-15\\\\65=x^2+2x-15-65\\\\x^2 +2x-80=0\\\\x^2 +10x-8x-80=0\\\\x(x+10)-8(x+10)=0\\\\(x-8)(x+10)=0$

x = 8 or x = -10

For the length:

when x = 8

$Length = 8 +5$

Length = 13 inches.

For the width:

when x = 8

$Length = 8 -3$

Length = 5 inches.
