Question

Express 0.4 uM to mmol/mL

Answer 1

0.4 * 10⁻⁶mol

Step-by-step explanation:

The unit conversion required are ,

1 μ M = 10⁻⁶ M

1 L = 1000 mL

1 mol = 1000 mmol

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 ,

Hence , the unit is ,

M = mol / L

from the question ,

0.4 μ M = 0.4 * 10⁻⁶ M

Now,

0.4 * 10⁻⁶ M = 0.4 * 10⁻⁶ mol / L

Since ,

1 L = 1000 mL

and ,

1 mol = 1000 mmol

0.4 * 10⁻⁶ mol / L = 0.4 * 10⁻⁶ * 1000 mol / 1000 mL = 0.4 * 10⁻⁶mol
