I just need help on chemistry i don't know how to do Stoichiometry

Cannizzaro determined that a certain compound of carbon and oxygen had a molecular mass of 44.0 u. This meant that a certain volume of this gaseous compound weighed 44.0 times as much as the same...

How many moles of gold atoms do 4.50x10^24 gold atoms constitute?

I need help solving

I have found the mols of the HCl solution and I have found the mols of the unknown M. I divided by the mass to get 53.89g/mol. What I did next was find the mols of NaOH by using the formula M=mols/L...

If you could work me through the steps, that'd be great. Thanks

How would I calculate the amount of each metal in my groups sample? And how do I make the values I calculate are expressed in terms of amount of metal per amount of soil? &My final answers are...

this question is for unit conversions in introductor chemistry

It is chemical quantities

Give the units for the rate constants for the following rate law: Rate = k[A]/[B]. Taking into account that sometimes the other concentration units may be used (e.g. NIST Chemical Kinetics...
