Calculate the mass (in grams) of lithium hydroxide that would be needed to produce 8.03 mol of lithium sulfate in the reaction below.
2 LIOH + H2S04 -> Li2SO4 + 2 H20

385g LiOH

Explanation:

Assuming the equation is balanced...

(8.03 mol Li2SO4) x (2 LiOH/ 1 Li2SO4)

= 16.1 mol LiOH ;

16.1 mol LiOH x (24g LiOH/ 1 mole LiOH) = 385g LiOH

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
