molecular formula for chemistry in Redox Stoichiometry?

Question

Silver iodide powder is added to a solution containing 39.8 L of dissolved hydrogen gas at that were dissolved in the water at SATP. What mass of silver iodide powder would react completely with the gas?

H2+2AgI--> 2HI+ 2Ag

Is this the correct molecular formula?

p.s this is for redox Stoichiometry

Answer 1

Stoichiometry, regular or redox, relies on the chemical reaction to be balanced. Your reaction is.

STEP 1. Convert the volume of H2 to moles. Since 1 mole occupies 22.4 L at SATP, divide 39.8 L/22.4 L per mole.

STEP 2. On a mole-to-mole basis, check the reaction. For each mole of H2, 2 moles of 2AgI are needed. So determine the moles of AgI for the problem.

STEP 3. Determine the molecular weight of AgI.

STEP 4. Multiply the number of moles of AgI from step 2 by the molecular weight.

Answer 2

i think that that explains it all
