Sodium bicarbonate is sometimes used to neutralize acid spills. if 2.0 l of 1.0 m h2so4 is spilled, what mass of sodium bicarbonate (nahco3) is required to neutralize all the h2so4?

168.0 g

Explanation:

First thing, write a balanced chemical equation:

n(H2SO4) = concentration * volume

                = 1.0 M * 2.0 L

                = 2.0 mol

According to the balanced equation, 1 mol of acid requires 2 mol of sodium bicarbonate. This means that 2 mol of acid requires 2 mol of sodium bicarbonate. What mass of sodium bicarbonate is this?

mass (NaHCO3) = number of moles * molar mass

                           = 2.0 mol * 84.0065 g/mol

                           = 168.0 g

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".
