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 = ?
To find the value of w , using the above formula , and putting the respected values ,
Molarity (M) = ( w / m ) / V ( in L)
0.5 = ( w / 329.24 ) / 1 L
w = 164.62 g
