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't accept my makeshift multiplication sign or an asterick. Anything up for suggestion for this particular website?

well, you have the conversion wrong. It is 1.1E3, or 1.1*10^3, which is right. I dont know how it is written at the website you are working with.
