A student found that the mass of the naphthalene collected was less than the mass determined by difference. What would account for the smaller amount of the naphthalene collected?

The naphthalene solid has a significant vapor pressure, as indicated by its strong odor. The solid naphthalene will evaporate, decreasing the mass of solid naphthalene present.
m collected + m evaporated = Delta m

Loss of product during transfer, incomplete recrystallization, or impurities mixed with the naphthalene could account for the smaller amount collected compared to the expected mass. Additionally, errors in measurement or calculation during the experiment could also contribute to the discrepancy.

The atomic weight of an element is determined by what?
The atomic weight of an element is determined by the weighted average of the masses of its isotopes, taking into account their abundance in nature. This value is typically found on the periodic table as the average atomic mass of the element.
What Is The Oxidation Number For Iodine pentoxide?
The oxidation number for iodine in iodine pentoxide (I2O5) is +5. This is determined by taking into account the overall charge of the compound and the known oxidation number of oxygen atoms in a molecule.
What is the oxidation number of sulfer in h2so4?
The oxidation number of sulfur in H2SO4 is +6. This is determined by balancing the overall charge of the compound, which is 0, and taking into account the known oxidation numbers for hydrogen (+1) and oxygen (-2).
What is the oxidation number of sulfur in the tetrathionate ion S4O62-?
The oxidation number of sulfur in the tetrathionate ion (S4O6^2-) is +5. This can be determined by setting up an equation where the sum of the oxidation numbers equals the charge of the ion, with the known oxidation number for oxygen (-2) and the overall charge (-2) taken into account.
How is the average mass number of an element is determained?
The average mass number of an element is determined by taking into account the abundance of each isotope of the element and their respective mass numbers. It is calculated by summing the products of the mass number of each isotope with its abundance, and dividing by the total abundance.
How do you account for the observed solubility of naphthalene and sodium chloride in water and in ether based on the nature of the bonds that exist in them?
The reason why naphthalene can be dissolve in ether and not in water is because of their polarity. Naphthalene is a non-polar molecule. so it can only dissolve with a non-polar molecule.

What is the suspense capital?
A suspense account is an account in the general ledger in which amounts are temporarily recorded. The suspense account is used because the proper account could not be determined at the time that the transaction was recorded. When the proper account is determined, the amount will be moved from the suspense account to the proper account.

What is the meaning of uncollectible accounts?
Uncollectible accounts refer to accounts receivable (money owed to a company by its customers) that are unlikely to be collected. These are typically debts that have become delinquent and the company has determined that collecting the payment is not feasible. The company may choose to write off these accounts as bad debt and remove them from its books.
