Sig Figs in 11.19

$\Delta G^{\circ}= \Delta H^{\circ} - T \Delta S^{\circ}$

$\Delta G^{\circ}= -RT\ln K$

$\Delta G^{\circ}= \sum \Delta G_{f}^{\circ}(products) - \sum \Delta G_{f}^{\circ}(reactants)$

Sig Figs in 11.19

For 11.19, the solution manual just gives the answers in 1 sig fig. However, shouldn't it have 2 sig figs since we are given temperature in 2 sig figs?

I feel like it should be 2 sig figs as well given the 25 degrees.

It should be two sig figs, but I wouldn't worry too much about it since we won't be penalized for improper sig figs on tests.
