When I have something like: Al(OH)3
would I set it up like this: 26.982(15.999+1.008)*3?

Best ResponseYou've already chosen the best response.0mole to grams conversions the question is: How many moles are in 98.3 grams of aluminum hydroxide, Al(OH)3

Best ResponseYou've already chosen the best response.5how many moles of \(\sf Al(OH)_3 \) do you have?

Best ResponseYou've already chosen the best response.0thats the question; it only gave grams for me to find that.

Best ResponseYou've already chosen the best response.5if you do not see a number before the name of the compound or molecule then it means there is only one mole.

Best ResponseYou've already chosen the best response.5do you see how the mole unit for a particular thing is canceled out algebraically?

Best ResponseYou've already chosen the best response.0yeah I see where it would be cancelled out. I just need to know how to find the molecular weight of the aluminum hydroxide.

Best ResponseYou've already chosen the best response.5whatever unit you're trying to convert out of, you need to divide by itself

Best ResponseYou've already chosen the best response.5molecular weight follows the conservation of mass so if you see Al it means there is 1 Al in there if you see \(\sf (OH)_3\) it means that there are 3 O's and 3 H's; the subscripts tell you how many there are for whatever each element that is enclosed in parenthesis

Best ResponseYou've already chosen the best response.5usually when there's 1, we do not write it out. it is just like saying a mole of something  it is implicit that the word "a" denotes 1

Best ResponseYou've already chosen the best response.5you're going to add all the weights of each elements in that molecule/compound

Best ResponseYou've already chosen the best response.5\(\sf \large Al(OH)_3 = [1 \times (weight_{Al})] + [3 \times (weight_{O}+weight_{H})] \)

Best ResponseYou've already chosen the best response.0so the answer is 78.003 correct?

Best ResponseYou've already chosen the best response.5I don't know the individual atomic mass units of each elements, that is something you need to reference to a periodic table.

Best ResponseYou've already chosen the best response.0@hwyl what about when it says: Ca3(PO3)2

Best ResponseYou've already chosen the best response.5Ca: \(3 \times \sf Ca \) P: \(2 \times \sf P \) O: \(2 \times 3 \sf ~ O \)
