The molar mass of lithium carbonate is equal to 73.9 g/mol. Answer the following questions. 1) What mass of lithium carbonate is required to prepare 500.0 mL of a 0.250 M Li2CO3 solution

9.2375 grams of lithium carbonate is required to prepare 500.0 mL of a 0.250 M Li₂CO₃ solution.

Explanation:

Molarity is a measure of the concentration of a substance and is defined as the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

Molarity is expressed in units .

In this case:

Replacing in the definition of molarity:

Solving

0.250 M*0.5 L = number of moles of solute

0.125 = number of moles of solute

If the molar mass of lithium carbonate is equal to 73.9 g/mol, then the required mass of the compound can be calculated by:

9.2375 grams of lithium carbonate is required to prepare 500.0 mL of a 0.250 M Li₂CO₃ solution.

explanation:

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".
