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
m/s is the correct answer of them.
<span>2 Al+6 HBr = 2 AlBr</span>₃ <span>+ 3 H</span>₂
2 moles Al --------- 6 moles HBr ----------- 3 moles H₂
3.22 moles Al ------ 4.96 moles HBr ----- ( moles H₂ )
moles H₂ = 4.96 x 3 / 6
moles H₂ = 14.88 / 6
= 2.48 moles of H₂
hope this helps!
