Molarity is moles/Liter. 0.150 M in 250mL is ¼ of 0.150 moles/L, or 0.0375 moles/0.25L. N a2S2O3 ⋅ 5H 2O just has the extra mass (moles) of water to consider. That is irrelevant to this problem because we are already given the molar mass for the compound. Web12 mrt. 2024 · So, only 1.67*10^-2 moles of sodium iodide will react fully until there is no more of it. The mole ratio between NaI and NaCl is 2:2=1, so if 1.67*10^-2 \ "mol of" \ NaI are used, then also 1.67*10^-2 \ "mol of" \ NaCl are created. Now, the question asks to find us the mass produced, ... sol l thermoplastics
