You decide to use absorbance to measure the resulting solution. You dilute 2.00 mL of the 25.0 mL solution with water in a 100 mL volumetric flask. The absorbance of the new diluted solution is 0.773. If the equation of the trendline from the standardization plot was y=1,134x, determine the mass of the LOCO3 in the original sample. The MW of LoCO3 is 128.52 g/mol.

Follow-up Question

Using the moles of Locust Carbonate calculated in the question above, calculate the volume of gas produced in the reaction with Locust Carbonate. Assume the gas behaves ideally and you are at standard temperature (T=293 K) and pressure (P=1.0 atm). 

 

Given that the total volume of gas produced in the complete reaction (both reactions combined) is 0.500 L, calculate the mass of Quakerium in the sample (Assume Qu is 34.02 g/mol and you are at standard temperature (T=293 K) and pressure (P=1.0 atm)).
