A sample of nitrogen gas has a mass of 48.6 grams. How many N2 molecules are there in the sample? molecules Submit Answer &
marysya [2.9K]

Answer:

There are 1.05  x 10²⁴ molecules in 48.6 g N₂

Explanation:

1 mol of N₂ has a mass of (14 g * 2) 28 g.

Then, 48.6 g of N₂ will be equal to (48.6 g *(1 mol/ 28 g)) 1.74 mol.

Since there are 6.022 x 10²³ molecules in 1 mol N₂, there will be

(1.74 mol *( 6.022 x 10²³ / 1 mol)) 1.05  x 10²⁴ molecules in 1.74 mol N₂ (or 48. 6 g N₂).

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
