LiOH+HBr---> LiBr +h20 If you start with 10.0 grams of lithium hydroxide, how many grams of lithium bromide will be produced?
kicyunya [14]
<span>LiOH+HBr---> LiBr +h20. Moles of LiOH = 10/24 = 0.41moles. According to stoichiometry, moles of LiOH = moles of LiBr = 0.41moles. Therefore mass of LiBr =moles of LiBr x molecular weight of LiBr = o.41 x 87 = 35.67g. Hope it helps </span>

How many grams of O are in 605 g of Na,O?
Elden [556K]

Answer:

2Na2O2+2H2O⟶O2+4NaOH

2×78g                           32g

156g of Na2O2 produces 32g of O2,

12g of Na2O2 produces =15632×12=10.66g.

Density of O2 at NTP=1.428g/mL.

DensityMass=Vol.

1.42810.66=7.46mL

Vol. of O2 at NTP is 7.46mL.
