If the government imposes a per-unit tax on a good with inelastic demand, what is the most likely effect on the quantity demanded of that good?

When the government imposes a per-unit tax on a good with inelastic demand, the quantity demanded of that good will not change much. Inelastic demand means that consumers will continue to buy nearly the same amount of the good even if the price increases. For example, if a tax is placed on essential medicine, people will still need to buy it despite the higher cost, because they cannot easily find substitutes. This happens because the good is necessary for them, so they are less sensitive to price changes. Therefore, the tax mainly affects the price consumers pay rather than the quantity they purchase.
