If I have box with volume 31.0 mL , what is the Liquid mass of the water?

• → Mass = Volume × Density

• But density of water is 1000 kgm^-3

• Volume is 31.0 mL = 31.0 cm^3 = 0.000031 m³

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
