A solution of H2SO4(aq) with a molal concentration of 5.25 m has a density of 1.266 g/mL. What is the molar concentration of thi
Igoryamba
<span>There are a number of ways to express concentration of a solution. This includes molarity and molality. Molarity is expressed as the number of moles of solute per volume of the solution.  MOlality is expressed as moles per kg solution. 

5.25 mol H2SO4 / kg solution ( 1 kg / 1000 g ) ( 1.266 g / mL ) ( 1000 mL / 1L ) = 6.6 M H2SO4</span>

Describe in detail how to prepare 500 ml of a 2.5 m calcium chloride solutiion
UkoKoshka [18]

No. of moles of calcium chloride = molarity × volume of solution in L

No. of moles of calcium chloride = 2.5 ×0.5 = 1.25 mole

No. of moles of calcium chloride = mass of calcium chloride / molar mass of calcium chloride

1.25 mole = mass of calcium chloride / 110.98 g/mol

mass of calcium chloride = 1.25 ×110.98 = 139 g

Amobarbital sodium react with ethanolic sodium hyrooxide
CaHeK987 [17]

Amobarbital (like all barbiturates) works by being incontestible to the GABAA receptor at either the alpha or the beta subunit.

<h3>What is the mechanism of amobarbital?</h3>

Amobarbital (like all barbiturates) works by binding to the GABAA receptor at either the alpha or the beta subunit. These are compulsory sites that are distinct from GABA itself and also distinct from the benzodiazepine binding site.

Amobarbital is a barbiturate classified as having a halfway duration of action, meaning that the effects of the drug can last from 4-6 amobarbital increases the effects of benazepril by apparatus: pharmacodynamic synergism.

So we can conclude that Amobarbital, 5-ethyl-5-isoamyl barbituric acid like all barbiturates.
