4) A granola bar has a mass of 42.9 g and the granola bar contains 26.20% honey

nata0808 [166]

<u>Answer:</u>

The percentage of honey in one granola bar is 26.02 percent.

<u>Explanation:</u>

The weight of 1 granola bar is 42.9 grams. The grams of honey that is present in one granola bar is equal to 26.02 percent of 42.9 = 11.16 g

Now the amount of honey in the factory is given as 189.5g the weight of total granola bars would be

$= 42.9/11.16 x 189.5= 728.25$

So no. of granula bars $=728.25/42.9 =16.9$ that can be Approximated to nearly 17

Now if one box has 6 bars then 17 bars will have to fit inside three boxes

In the explosion of a hydrogen-filled balloon, 0.60 g of hydrogen reacted with 4.8 g of oxygen. how many grams of water vapor ar

Kaylis [27]

First write the balanced equation of this reaction:
2H2 + O2 —> 2H2O

mol of H2= 0.60 gH2/2.02 gH2 = 0.297 mol
There are 2 mol of H2 for every 2 mol of H2O so the number of mol of H2 is equal to the number of mol of H2O.
g of H2O = 0.297 mol H2O • 18.02 gH2O = 5.35 g H2O

Do the same thing for O2:
mol of O2 = 4.8 gO2/32.0 gO2 = 0.15 mol of O2
There is 1 mol of O2 for every 2 mol of H2O so multiply 0.15 • 2 to get the number of mol of H2O
g of H2O = 0.30 mol H2O • 18.02 gH2O = 5.41 g H2O

The correct answer is 5.35 g H2O (or 5.4 g if checking significant figures) because O2, in this case, is the limiting reactant of this reaction.
