Lithium hydroxide reacts with hydrobromic acid to produce lithium bromide and water If you start with then grams of lithium hydroxide how many grams of lithium bromide will be produced?

Answer 1

Balanced equation:

LiOH + HBr ---> LiBr + H₂O

Here, we aim to convert the mass of LiOH to mass of LiBr. In this formula, the product (LiBr) takes x, and the reactant (LiOH) takes y. Here's how it goes. (? = coefficient in the balanced equation)

mass of x = (mole of y) * (? mol x / ? mol y) * (molar mass of x)

mass of LiBr = (10 g / 23.95 g/mol) * (1 mol LiBr / 1 mol LiOH) * (86.85 g/mol LiBr)

mass of LiBr = 36.3 g (Answer)

Answer 2

mol of LiOH = 10g LiOH/ 23.949g/mol LiOH

= 0.418 mol LiOH

mol of LiBr = 1/1 * 0.418

= 0.418 mol LiBr

mass of LiBr = 0.148 mol/ 86.845 g/mol

= 36.301 g LiBr

Answer 3

There are 2.85 grams in a dime
