What is the mass of a formula unit of cuprous sulfide?
The mass of a formula unit of cuprous sulfide (Cu2S) is 159.152 g/mol.
The molecular formula for hydrogen sulfide is H2S. What does the formula indicate about the composition of a 1.0-gram sample of hydrogen sulfide?
The molecular formula H2S indicates that in every molecule of hydrogen sulfide, there are 2 atoms of hydrogen and 1 atom of sulfur. Therefore, in a 1.0-gram sample of hydrogen sulfide, there would be 0.67 grams of hydrogen (2/3 of 1.0 grams) and 0.33 grams of sulfur (1/3 of 1.0 grams).
What is the mass in grams of a single formula unit of silver chloride?
The molar mass of silver chloride (AgCl) is approximately 143.32 g/mol. Since a formula unit represents one molecule of the compound, the mass in grams of a single formula unit of silver chloride is 143.32 grams.
How many grams are in 3.3 miles of potassium sulfide?
It is not possible to convert miles directly to grams without additional information such as the density or molecular weight of potassium sulfide. Can you provide that information?
What is the mass of 1.474 mol of potassium sulfide?
To find the mass of 1.474 mol of potassium sulfide, you need to multiply the number of moles by the molar mass of potassium sulfide. The molar mass of potassium sulfide (K2S) is approximately 110.26 g/mol. Therefore, the mass of 1.474 mol of potassium sulfide is about 162.62 grams.

What is the formula for potassium hydrogen sulfide?
The formula for potassium hydrogen sulfide is KHS. Another name for this inorganic compound is potassium hydrosulfide. Its molar mass is 72.17 grams per mole, and it is soluble in water.
How many grams of sodium sulfide are formed if 1.90 of hydrogen sulfide is bubbled into a solution containing 2.53 of sodium hydroxide assuming that the sodium sulfide is made in 91.0 yield?
The equation for the reaction specified is 2 NaOH + H2S -> Na2S + H2O. Therefore, if the yield were 100 %, two formula masses of sodium hydroxide are required to produce one formula mass of sodium sulfide. The gram formula mass of NaOH is 40.00 and that of sodium sulfide is 78.04. The specified number of grams of sodium hydroxide corresponds to 2.53/40.00 or 0.06325 formula masses and therefore would provide half this many formula masses of sodium sulfide, for a mass of (0.06325)(78.04)/2.000 or 2.568 grams of sodium sulfide. Since the yield is specified as 91.0 %, the actual amount of sodium sulfide produced is 2.25 grams, to the justified number of significant digits.
Why do you need 40 grams of calcium and 32 grams of sulfur to make 72 grams of calcium sulfide?
From the periodic table, calcium has a molar mass of 40.078g/mol and sulfur has a molar mass of 32.065g/mol. The formula for compound formed from calcium and sulfur, calcium sulfide is CaS. The molar mass of CaS is 72.143. So, if you round the numbers, 40g of Ca + 32g of S will produce 72g of CaS.
How many grams of aluminum hydroxide are obtained from 17.2 grams of aluminum sulfide?
To determine the grams of aluminum hydroxide obtained from 17.2 grams of aluminum sulfide, we need to consider the stoichiometry of the reaction between aluminum sulfide and water to form aluminum hydroxide. Given the balanced chemical equation, we can calculate the molar mass of aluminum hydroxide and use it to convert the mass of aluminum sulfide to grams of aluminum hydroxide formed.
What is the mass in grams of a single formula unit of silver chloride?

How many moles are in 125.00 grams of sodium sulfide?
There are at least three kinds of sodium sulfide, but assuming that the question refers to the most common one with the formula Na2S, its gram formula mass, the mass corresponding to molar mass for covalently bonded compounds, is 78.04. Therefore 125.00 constitutes 125.00/78.04 or 1.6017 "moles".
How many grams of iron II sulfide have to react with hydrochloric acid to generate 12 g of hydrogen sulfide?
To calculate the grams of iron II sulfide needed, we start by finding the moles of hydrogen sulfide produced. This is done by dividing the given mass of hydrogen sulfide by its molar mass. Then, we use the balanced chemical equation to determine that for every 4 moles of hydrogen sulfide, 1 mole of iron II sulfide is needed. From this, we find the grams of iron II sulfide required by multiplying the moles of iron II sulfide by its molar mass.
