I have figured the volume at .6472L of O2 at STP when 12.51 g of HgO is heated but the answer tells me to check my sig figs. I have tried .6470 and .6472. any ideas what they are asking for?
0.65 you want to match the sig figs in the problem to your answer so in this case 2 spaces after the decimal
so I should enter0.65 or .65 or does it matter?
