it looks like piss

anonymous · Answer

some guy from crowd can you help me?

mrnebula · Answer

yea can u help me now

mrnebula · Answer

sins i said piss

anonymous · Answer

For the first part, you need to figure out how much mass was gained by the tin.

Do you understand why the sample was heated until it appeared dry?

mrnebula · Answer

i thought it was piss

mrnebula · Answer

i wonder if piss is on the periodic table

anonymous · Answer

it is a 2.12 difference

anonymous · Answer

after I added the tin

anonymous · Answer

Good. Now, if the molar mass of tin is 118.71, how many moles of tin did you start with?

anonymous · Answer

I started with 0 but then I added 2,12 in?

anonymous · Answer

You added 2.12 grams of oxygen, but the amount of tin in the dish remained constant throughout the reaction. You need its molar mass to figure out the empirical formula of the compound produced by the reaction.
