What is the molarity of the acetic acid? $($Check a statement for the correct final answer $($four options$)$ and correct s$.$f reasoning $($next four options$))$

Student work:

$\frac{0\mathrm{.}008433(mol)\text{a}\text{c}\text{e}\text{t}\text{i}\text{c}\text{a}\text{c}\text{i}\text{d}}{0\mathrm{.}01000(L)}=0\mathrm{.}8433M$ acetic acid

Choose one or more:

$0\mathrm{.}8M.$

$0\mathrm{.}84M$

$0\mathrm{.}843M$

$0\mathrm{.}8433M$

The answer should have $1s.$f since the zeroes in $0\mathrm{.}01000L$ are not significant.

The answer should have $2$ s$.$f$.$ because $0\mathrm{.}01000$ L has $2$ s$.$f$.$

The answer should have $3$ s$.$f$.$ because $0\mathrm{.}008433$ mol has $3$ s$.$f$.$

The answer should have $4$ s$.$f$.$ because $0\mathrm{.}01000L$ and $0\mathrm{.}008433$ mol both have $4$ s$.$f$.$
