Answer:
5.076 * 10 ⁻¹² M
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 ,
w = given mass of epinephrine = 0.00000093 g
V = 1 L
Since , the molecular mass of epinephrine = m = 183,204 g/mol
M = ?
In order to determine the molarity of epinephrine , the above formula is used , by putting the respected values ,
Molarity (M) = ( w / m ) / V ( in L)
M = ( 0.00000093 g / 183,204 g/mol ) / 1 L
M = 5.076 * 10 ⁻¹² M
