Mr. Avogadro has set up 4 jars with one mole of each the following substances: 1. Iron
2. Sodium Chloride
3. Sodium Bicarbonate (NaHCO3)
4. Aluminum
His clever and intelligent students notice that all of the amounts of the various
substances are different from one another, even though they are all ONE
MOLE. Explain the reason why each amount in the jar is different in terms of
the mole. Then, calculate the molar mass for each of the substances, Circle your
your answers and include the unit used for molar mass.

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

236 cm 16 time 12 = 192

6 times 7 = 42

192+42

a = (-2, 0)

b= (-4, 0)

c = (-5,2)

d = (-1,2)
