A solution of NH3 was prepared by diluted 8.29 (+/- 0.03) mL of 27.62 (+/- 0.50) wt% NH3 [density=0.899 (+/- 0.003) g/ml] up to 564.0 (+/- 0.2) mL. The molecular mass of NH3 is 17.0305 g/mol. Find the concentration of NH3 in M. Assume negligible uncertainty in the molar mass of NH3, and use error propagation to calculate the absolute uncertainty for the answer.

You prepared a diluted NH3 solution by diluting 8.46 (Â±0.04) mL of 28.0 (Â±0.5) wt% NH3 [density = 0.899 (Â±0.003) g/mL] up to 500.0 (Â±0.2)ml. What would be the final diluted concentration of NH3, (10pt) and its uncertainty? (10pt)

A solution was made by combining 145 (Â±1) mL of 0.250 (Â±0.003) M NaCl with 275.0 (Â±0.5) mL of 6.00 (Â±0.01) wt% NaCl (assume this solutionâs density is 1.0413 g/mL and the molar mass of NaCl is 58.443 g/mol, both with negligible error) in a 500.00 mL volumetric flask, and filling with water up to the line.

How many mmol of NaCl are in the final solution? Include absolute error in your number of millimoles and round your answer to an appropriate number of sig figs.

(HINT: First find the number of millimoles of NaCl, ignoring the error. Then go back and propagate error properly through each calculation step. )
