Question

A 1.250 g mass of standard aspirin is dissolved in approximately 20 mL of 1 M NaOH. This solution is added to a 250-mL volumetric flask and diluted to the mark with DI water. How many grams per mL of aspirin are in the resulting solution? (Note that a 250-mL volumetric flask has a precision of 0.01 mL and the amount of NaOH added has no bearing on the significant figures in the final concentration.) (g per mL)

Answer 1

1.250/250 = ?

Answer 2

.005
