If a sample is analyzed and the line intensity registers a relative color intensity of 15, what is the approximate molarity of morphine in the sample? (note: the molecular formula of morphine is c17h19no3)

The molarity of morphine is 2.45 * 10^-9 M

Explanation:

Step 1: Data given

Molecular formula of morphine = C17H19NO3

Atomic mass of C = 12.01 g/mol

Atomic mass of H = 1.01 g/mol

Atomic mass of O = 16.0 g/mol

Atomic mass of N = 14.0 g/mol

a relative color intensity of 15 corresponds to a morphine concentration of 0.7 ng/mL

Step 2: Calculate molar mass of morphine

Molar mass = 17 * 12.01 + 19*1.01 + 14.0 + 3*16.0

Molar mass morphine = 285.36 g/mol

Step 3: Calculate the molarity of morphine

Molarity = 0.7 ng/mL * (1g / 10^9 ng ) / (285.36 g/mol) * (1000 mL)

Molarity = 2.45 * 10^-9 M

The molarity of morphine is 2.45 * 10^-9 M

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

i think option no d is the correct answer
