Answer:

25.2 grams HOAc

Explanation:

For solution preparations a simple formula for determining amount of solute needed is ...

from solid stock => grams = Molarity x Volume (Liters) x formula wt of solute

∴ grams HOAc = M·V·f.wt = (0.839M)(0.500L)(60.05g/mol) = 25.2 grams HOAc

Mixing => Transfer gram wt of solute to mixing container and dilute up to but not to exceed total needed volume.
