40.0g of ethanol, C2H5OH, is dissolved in 150.0L of solution. Determine the molarity of ethanol in this solution.

The molarity of ethanol is 5.8*10⁻³ M.

Explanation:

Molar concentration is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species.

Molarity or Molar Concentration is the number of moles of solute that are dissolved in a certain volume. It is calculated by dividing the moles of the solute by the volume of the solution:

Molarity is expressed in units .

Being the molar mass of ethanol 46 , then the number of moles that 40 grams of ethanol contain is calculated by:

So, being:

Replacing in the definition of molarity:

Solving:

Molarity= 5.8*10⁻³ M

The molarity of ethanol is 5.8*10⁻³ M.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

im pretty sure its b
