If one wished to obtain 0.15 moles of glacial acetic acid, how many milliliters of glacial acetic acid should be obtained? Enter only the number with two significant figures.

Aminolevulinate dehydratase (ALAD) is an enzyme that relies on zinc as a coenzyme. A zinc ion binds to the ALAD active site, where it forms favorable interactions with the side chains of three amino acids.

Calculate the mass of solid CuSO4∙5H2O (±0.1 g) needed to prepare 25.00 mL of 0.10 M Cu2 + solution. When calculating the molar mass, include the full formula of the CuSO4∙5H2O (s) - its formula is called "copper (II) sulfate pentahydrate" and
