Molarity is moles/Liter. 0.150 M in 250mL is ¼ of 0.150 moles/L, or 0.0375 moles/0.25L. #Na_2S_2O_3 * 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. small hard lump on my arm

WebMay 23, 2016 · The equation of the formula is M = mol L In order to find the mass we first need to solve for the moles. mol = M L M = 0.400 moles = ? L = 250.0 mL or 0.25 L 0.400M (0.25L) = (?mol) 0.100molof N aOH Now we can calculate the grams be converting moles to grams. N a = 22.98g O = 15.99g H = 1.01g N aOH = 39.98g 0.100molN aOH x 39.98gN … WebFeb 28, 2024 · Explanation: Concentration = Moles of solute (moles) Volume of solution (L) Thus Concentration × volume = moles of solute 0.205 ⋅ mol ⋅ L−1 ×0.250 ⋅ L = Moles of solute = 0.0513 ⋅ mol, an answer in moles as required. And thus mass of NaOH = moles × molar mass = 0.0513 ⋅ mol × 40.0 ⋅ g ⋅ mol−1 = 2.05 ⋅ g Answer link WebFerroxcube offers a wide range of materials for different frequency bands, thermal conditions and type of noise to be suppressed, with complete data and characterization … Stock Checker,High Performance Ferrite.
