A gas occupies 40.0 mL at -123°C. What volume does it occupy at 27°C, assuming pressure is constant?

80.0 mL

Explanation:

V1/V2 = T1/T2

T1 = 273 -123 = 150K

T2 = 273 +27 = 300 K

40.0 mL/V2 = 150K/300K

V2 = 40.0 mL*300K/150K = 80.0 mL

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".
