How many grams of H2O are produced if you have 8.0 mol of H2 in the reaction 2H2 + O2 2H2O?

h230  8.0 mol =h2330

Step-by-step explanation:

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

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.
