chemistry
calculate the energy required to raise the temp. of 170.0 g of silver (specific heat = .24 joules/celsius times grams) from 273K to 301K. I know the equation and I got 1142.4 joules but need to get to 2 sig figs, so I converted it to 1.1 x 10^4 which is right, but it doesn'...

chemistry
everything I tried was wrong for the conversions and the sig figs still don't make sense. How do you make a big sig fig into a smaller one using 8339? Please give an example.

chemistry
for a manometer flask diagram, if ha = 134 mm, how do I convert to torr, Pa, and atm with the right amount of sig figs? Related to sig figs, how do I get the right amount of sig figs (which is 2) with 8339?
