(Correction) You mixed 1.150g Na2C204 with 0.450g KMNO4 in excess aqueous acid. What apparent mass and true mass of CO2 will the resulting reaction yield? note of the following information: • Use the mass of CO2 you calculate above as the apparent mass. No need to convert the masses of Na2C204 and KMNO4 into true masses first. • The unbalanced chemical equation of the reaction is as follows: H2C2O4 + MnO4 + H* → CO2 + Mn2+ + H2O • The pertinent formula masses are as follows: Reagent Formula Mass (g/mol) Na2C204 134.00 KMNO4 158.03 CO2 44.0095 • The formula for the true mass is as follows: The true mass m can be calculated from the observed mass, m’. d 1- d m= m' d, 1- do a Where: da is the density of air (0.001 2 g/mL at 1 bar and 25°C) dwis the density of the calibration weights (8.0 g/mL) d, is the density of the object being weighed.

Please solve both parts qs, will provide helpful ratings.
Recall that the formula for ΔHrxn = [(-Ccal)(moles of limiting reactant)/(ΔT)]If the actual concentration of the sodium hydroxide used in the calibration part of the experiment was lower than the stated value, will the value of Ccal increase, decrease, or remain the same? Please explain. How about if the actual concentration of the sodium hydroxide used in the calibration part of the experiment was lower than the stated value. However, the NaOH solution used in the determination of ΔHrxn was of the correct concentration. Will the magnitue of ΔHrxn increase, decrease, or remain the same? Please explain.

My answer is not coming up as an option. I was solving for moles of each, then adding them up and then dividing by mole frac of meth. But I must be doing something wrong please advise
hi can you please calculate % yield also, i have put 0.18g in the table but in the lab, some of it was taken out so 0.17g of the crude product was used for recrystallisation process, now i am not sure which value to use for the %yeilds. can you also please check if my other calculations are right.
