To find how much antimony is in a given amount of stibnite, it is important to understand the proportion of antimony in the compound by mass. First, calculate the total molar mass of Sb\u2082S\u2083 by adding the molar masses of its elements, considering their number of atoms. The molar mass reflects how much one mole of the compound weighs.<\/p>\n\n\n\n<p>Next, determine what fraction of that molar mass is due to antimony alone. Since there are two antimony atoms, multiply the atomic mass of Sb by two and divide by the total molar mass of stibnite. This fraction tells us the percentage by mass of antimony in the compound.<\/p>\n\n\n\n<p>Finally, multiply the given mass of stibnite by this fraction to find the actual mass of antimony in that sample. This method is a standard approach in chemistry for calculating the mass of a component within a compound, using the concept of molar masses and mass fractions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What mass of antimony is contained in 106g of stibnite, Sb2S3?
