Determine the mass in grams of pentane that must be added to 67 g of benzene to make a 1.04 m solution. give your answer to 2 decimal places.

5.02 g pentane.

Explanation:

Hello,

Molality is given by:

Since the mass of the solvent (benzene) is 67 g, its value in kg is 0.067 kg because it is needed in that way in the formula. Now, solving for the moles of pentane (solute):

Converting from moles to grams of pentane, we get the final

Best regards.

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.
