Hey...
Use the molarity formula
M=moles/L and then convert to grams
0.07268*0.15=moles
<span>0.010902 mol
</span>Pb(NO3)2
1 mole=331.22g
0.010902 moles=
3.61 g
Answer:
See below
Explanation:
Molarity = moles/Volume in Liters = (grams/formula wt)/Vol in Liters
=> Grams of solute = Molarity x Vol in Liters x formula wt
= (0.250M)(0.750L)(212.3g/mol)
= 39.8 grams
The only statement which I've found correct is the first option represented above: one variable of a gas affects only one additional variable of the gas. I choose this one because when one <span>variable increases or changes in any measure the other should change the same constant rate. I hope it's clear, regards!</span>
