100 mg/dl is a typical blood concentration of glucose. the molecular weight of glucose is approximately 180 daltons. what is the molarity of this solution in millimoles?

The molecular weight of glucose is approximately 180 daltons so each mol of glucose will be equal to 180g glucose. The concentration of glucose in the blood would be: 100mg/dl * 1 mol/180g= 5.55 mol/dl * 10^-4

Molar is expressed as mol per liter, so you need to change the volume into liters. The calculation would be: 5.55 mol/dl * 10^-4 * 10dl/liter= 5.55 * 10^-3 M= 5.55  millimoles

K(x) = (1/4)^x

(1,4) when x = 1, k(1) = (1/4)^1 = 1/4FALSE
(3, 1/64) when x = 3, k(3) = (1/4)^3 = 1/64TRUE
(-1,4) when x = -1, k(-1) = (1/4)^-1 = 4TRUE
(0, 1/4) when x = 0, k(0) = (1/4)^0 = 1FALSE

answer
(3, 1/64)
(-1,4)
