Question- When aqueous solutions of K2SO4 and Pb(NO3)2 are combined, PbSO4 precipitates. Calculate the mass, in grams, of the PbSO4 produced when 1.74 mL of 0.154 M Pb(NO3)2 and 3.64 mL of 0.75 M K2SO4 are mixed. Calculate the mass to 3 significant figures.
Please explain above problem in step by step manner so I can easily understand it

Type your question hereA 0.1390-g rock sample of unknown concentration was dissolved in HCl and diluted to 100.0 mL. Aliquots of 10.00 mL of this unknown solution were added to different volumes of a 2.08 ?g/mL Ca standard solution and diluted to ..
The absorption rate constant is smaller than the elimination rate constarnt. Therefore, the terminal decline of the plasma concentration versus time curve reflects absorption not elimination.
Consider the following reaction (assume an ideal gas mixture). 2NOBr(g) ? 2NO(g) + Br2(g) A 3.0-L vessel was initially filled with pure NOBr, at a pressure of 3.6 atm, at 300 K. After equilibrium was reached,
