The KMnO4(aq) solution was prepared with 1.5 grams of KMnO4(s) dissolved into 1.0 L of water, calculate molar mass of the potassium permanganate and the  

[Formula Weight = molar mass of the oxalate ion = 88.02 grams/mole] % C2O4-2 = [(mass of C2O4-2)/(mass of green salt sample)] x 100 With the completion of this experiment, the percent composition of the green salt, KxFe(C2O4)y.zH2O, has been completely determined experimentally.

2.74 mol KMnO4 x 158.03 g KMnO4/1 mol KMnO4 = 433.0022 g KMnO4 . Sig figs 433 g KMnO4 2009-11-11 · KMnO4= KCI= Na2SO4= Ca(NO3)2= Al2(SO4)3= CuSSO4x5H2O= does anyone know how to solve these questions? Is there a rule to it i need to know Formula in Hill system is MnO4: Computing molar mass (molar weight) To calculate molar mass of a chemical compound enter its formula and click 'Compute'. In chemical formula you may use: Any chemical element. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al. therefore, Eq. wt. of KMnO4 = 158.04/5 = 31.61 grams/equivalent 2. KMnO4 as an oxidizer in basic media: MnO4- + 2H2O + 3e- --> MnO2 (s) + 4OH- (gained 3 electrons) or, 2.74 = weight in gram of KMnO4/158 or, weight in gram of KMnO4 = 2.74 × 158 g = 432.92 g hence, mass in gram of 2.74 mol of KMnO4 is 432.92g 1 moles KMnO4 to grams = 158.03395 grams.

KMnO4 is a dark purple crystal at room temperature. It is soluble in water. Its melting point is 240 ̊C (464 ̊F), density 2.7 g/cm3. KMnO4 is a strong oxidizing agent. It is widely used for prevent infection, water purification etc. Example Reactions: Equivalent weight can be calculated by using the formula Equivalent weight = Molar mass/number of electrons lost or gained (n) The molecular mass of KMno4 = 158.04g gram formula mass.wmv - YouTube.

[Formula Weight = molar mass of the oxalate ion = 88.02 grams/mole] % C2O4-2 = [(mass of C2O4-2)/(mass of green salt sample)] x 100 With the completion of this experiment, the percent composition of the green salt, KxFe(C2O4)y.zH2O, has been completely determined experimentally. Write the formula for each compound below. Then determine its molar mass.

Potassium permanganate (KMnO 4) has a molar mass of 158.034 g/mol (to get this just add up the masses of each element * how many there are) Manganese 

SDS; TDS; COA. Prix recommandés seulement. Pour voir vos prix,  The mass in grams of a mole of N2 molecules (its molar mass) is obtained by summing the molar masses The formula for potassium permanganate is KMnO4. 35.2 mł = 0.05843 mol KMnO4. 1000 m2 Moles of KMnO4 in the second solution: From the mass of KHP and its molar mass, we can calculate moles of KHP. Molar mass of KMnO4 = 158.033949 g/mol This compound is also known as Potassium Permanganate..

or, 2.74 = weight in gram of KMnO4/158 or, weight in gram of KMnO4 = 2.74 × 158 g = 432.92 g hence, mass in gram of 2.74 mol of KMnO4 is 432.92g
