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.


What is the mass percent of hydrogen in ammonium phosphate NH4 3PO4?

To find the mass percent of hydrogen in ammonium phosphate NH4 3PO4, first calculate the total molar mass of the compound. Then, determine the molar mass contributed by hydrogen. Finally, divide the molar mass of hydrogen by the total molar mass of the compound and multiply by 100 to get the mass percent.


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.


Calculate the mass in 3.3 moles of potassium sulphide?

To calculate the mass of 3.3 moles of potassium sulfide, you would first determine the molar mass of K2S. The molar mass of potassium (K) is 39.1 g/mol and sulfur (S) is 32.1 g/mol. Therefore, the molar mass of K2S is 39.1*2 + 32.1 = 110.3 g/mol. Multiply this molar mass by 3.3 moles to find the mass.


What is the Mass in Grams of 1.50 moles of hydrogen peroxide?

The molar mass of hydrogen peroxide (H2O2) is 34.01 g/mol. To find the mass of 1.50 moles, you would multiply the number of moles by the molar mass: 1.50 moles * 34.01 g/mol = 51.015 grams. So, the mass of 1.50 moles of hydrogen peroxide is 51.015 grams.

Hydrogen sulfide occupies 278.2 cm3 at 26oC and standard pressure What is the mass of the hydrogen sulfide?

To find the mass of hydrogen sulfide, we need to use the ideal gas law equation. The molar volume of an ideal gas at STP (standard pressure and temperature) is 22.4 L/mol. First, convert the given volume to liters (0.2782 L), then calculate the number of moles using the ideal gas law. Finally, multiply the number of moles by the molar mass of hydrogen sulfide (34.08 g/mol) to find the mass.


What is the mass percentage of strontium in strontium sulfide?

To calculate the mass percentage of strontium in strontium sulfide, you need to know the molar mass of strontium sulfide (SrS), which is 119.63 g/mol. The molar mass of strontium (Sr) is 87.62 g/mol. To find the mass percentage, you would divide the molar mass of strontium by the molar mass of strontium sulfide, and then multiply by 100. This would give you the mass percentage of strontium in strontium sulfide, which is approximately 73.2%.


How do you find moles of hydrogen?

To find the moles of hydrogen, you can divide the given mass of hydrogen by its molar mass. The molar mass of hydrogen is approximately 1 g/mol. So, moles of hydrogen = mass of hydrogen (in grams) / molar mass of hydrogen (approximately 1 g/mol).


What gas CH4 OR H2S heavier?

H2S (hydrogen sulfide) is heavier than CH4 (methane) because the molar mass of sulfur (S) is greater than the molar mass of carbon (C). This difference in molar masses results in hydrogen sulfide being denser and therefore heavier than methane.


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.
