Some chemical compounds are listed in the first column of the table below. Each compound is soluble in water. Imagine that a few
arsen [322]

Ionic substances produce ions in solution while molecular substances produce molecules in solution.

<h3>What is a solution?</h3>

A solution is a combination of solute and solvent. The species that occur in solution depends on the type of substance that was dissolved. Since the table is not shown, we do not know exactly what compounds were dissolved in solution.

Generally, if an ionic substance is dissolved in solutions that ions are present in the solution. If a molecular substance is dissolved in solution, molecules are present in solution.

A sample of lsd (d-lysergic acid diethylamide, c24h30n3o) is added to some table salt (sodium chloride) to form a mixture. given
spin [16.1K]
1) All the CO2 comes from the C24 H30 N3 O

2) To balance C from CO2 with C from C24, the ratio of cC24 H30 N3 O to CO2 is 24 / 1

3) Convert 1.20 g of CO2 to number of moles

number of moles = mass in grams / molar mass

mass = 1.20 g

molar mass = 12.01 g/mol + 32.00 g/mol = 44.01 g/mol

number of moles = 1.2 g / 44.01 g/mol = 0.0273 mol

4) proportion

1 mol C24 H30 N3 O / 24 mol CO2 = x / 0.0273 mol CO2

=> x = 0.0273 mol CO2 * 1 mol C24H30N3O / 24 mol CO2 = 0.00114 mol C24H30N3O

5) Convert 0.00114 mol C24H30N3O to grams

molar mass = 376.5 g/mol

mass = 0.00114 mol * 376.5 g/mol = 0.429 g

6) mass percent in the mixture

mass percent = (mass of lsd / mass of mixture) * 100 = (0.429g / 1.0g) * 100 = 42.9%

Answer: 42.9%
