how many grams of lithium hypochlorite are there in .762 moles

Question

ipwnbunnies · Answer

Do you know the molecular formula for lithium hypochlorite?

ipwnbunnies · Answer

Are you supposed to figure it out yourself, or no?

anonymous · Answer

its LiClO and im just totally lost on this question

anonymous · Answer

Ive worded it exactly how it is shown to me

ipwnbunnies · Answer

I believe it is actually Li2ClO, because the polyatomic ion ClO has a -2 charge.

ipwnbunnies · Answer

Oh it is -1 charge lol. I was thinking bout carbonate and it's ions sorry.

ipwnbunnies · Answer

Right, so LiClO. We need to find the molar mass of this compound which is easy when we have a periodic table. MM of LiClO = MM of Li + MM of Cl + MM of O.

ipwnbunnies · Answer

The molar mass of LiClO will be how much mass is in one mole of LiClO. Finally, multiply this by 0.762 mol to get your final answer.

anonymous · Answer

i have the molar mass already. its 58.39

anonymous · Answer

ok thank you. idk why these questions are so confusing for me. i understood it in class

ipwnbunnies · Answer

Lol, it's alright. Good, so that means 1 mole of LiClO has a mass of 58.39g. We need the mass of 0.762 moles, so we expect the mass to be less than 58.39g. 
All we do is 0.762mol*58.39(g.mol) to find the mass of 0.762 mol. Hope that helps.

it did. thanks
