Answer:

percentage of red skittles = 22%

percentage of skittles that are not green = 74%

Explanation:

total skittles = 50

yellow = 12

orange = 9

red = 11

green = 13

purple = 50-12-9-11-13

= 5

1) percentage of red skittles

\frac{red \: skittles}{total \: skittles}  \times 100

\frac{11}{50}  \times 100

\frac{22}{10}

22\%

2) percentage of skittles that are not green

\frac{total \: skittles - green \: skittles}{total \: skittles} \times 100

\frac{50 -13 }{50}  \times 100

\frac{37}{50}  \times 100

74\%

The molecular weight of potassium ferricyanide is 329.24 grams/mol. How would you make 1 liter of a 500mM potassium ferricyanide
True [87]

Answer:

w = 164.62 g

Explanation:

molarity of a solution is given as -

Molarity (M)  =  ( w / m ) / V ( in L)

where ,

m = molecular mass ,

w = given mass ,

V = volume of solution ,

From the question ,

M = 500 mM = 0.5 M

( since , 1 mM =  1 / 100 M)

As we know , the molecular mass of potassium ferricyanide = 329.24 g/ mol

V = vol.of solution = 1 L

w = ?

<u>To find the value of w , using the above formula , and putting the respected values , </u>

Molarity (M)  =  ( w / m ) / V ( in L)

0.5  =  ( w / 329.24 ) / 1 L

w = 164.62 g
