Hi, so I need help with my chemistry homework and I'm not sure how to go about these problems:
I don't just want the answer, I would like how you got it, step by step.
1.) How many molecules are there in 14.5g FeCl3?
2.) How many mols are there in 15.0g Ba2S2?
3.) How many molecules are there in 4.9 mol NaCl?
4.) The active indgredient in the over the counter drug called Pepto-Bismol is bismuth subsalicylate (C7H5BiO4). What is the percent composition of oxygen within this compound?
5.) Calculate the percent composition of nitrogen and hydrogen in NH4C2H3O2?
I just don't understand this at all. If anyone can help me in any way I would really appreciate it.
Thanks.
