Na2CO3 * __ H2O. Fill in the blank...?
Its a lab that I am doing.
Crucible + Lid : 37.18g
Crucible + Lid + Na2CO3 * _ H2O : 41.15g
Crucible + Lid + Na2CO3 : 39.54g
m of Na2CO3 * _ H2O : 3.97g
m of H2O : 1.61g
m of Na2CO3 : 2.36g
Moles of Na2CO3 := 2.36 / 105.99
= 0.0223 moles
Moles of H2o = 1.61 / 18.02
= 0.0893 moles
Ratio = 0.0893 / 0.0223
= 4
Am I right??

I can't stop listening to Kid Cudi. I wish I had the talent of Ezra Koenig. I can't stop thinking about creating a blog. The last song I listened to at full blast was Fat Bottom Girls by Queen. I love my Mom. Ezra Koenig is my favorite vocalist. Hugs makes me feel better when I am down. If I could meet anyone in the world that would be Kanye West. The last music video I watched was School of Seven Bells - "Half Asleep". I am soooo happy I met Cypress Davis. Vampire Weekend will be a band that I will listen to for the rest of life. I am a Martian. Karen O. is a sexy beast! ;)
