Answer:

9

Step-by-step explanation:

2(H2) + 02 -> 2(H2O) this is a correct balanced equation

now to solve for grams of H20 with 8 grams of O2 you must turn 8 grams O2 into moles then use the coefficients of the O2 and the H2O, then turn moles of H2O into grams of H20.

8 grams O2 x 1 mol O2 / 32 grams O2 (molar mass)

2 mol H20 (coefficients) / 1 mol O2 (coefficients)

18.02 grams H2O (molar mass) / 1 mol H20

this is 9 grams H20
