<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
So no. of granula bars that can be Approximated to nearly 17
Now if one box has 6 bars then 17 bars will have to fit inside three boxes
Answer:
Explanation:
= Mass of metal = 19 g
= Specific heat of the metal
= Temperature difference of the metal =
V = Volume of water = 150 mL =
= Density of water =
= Specific heat of the water = 4.186 J/g°C
= Temperature difference of the water =
Mass of water
Heat lost will be equal to the heat gained so we get
The specific heat of the metal is .
Answer:
26.67 mol HCl
Explanation:
Al(OH)₃ + 3HCl → AlCl₃ + 3H₂O
In order to solve this problem, we need to c<u>onvert Al(OH)₃ moles to HCl moles</u>.
To do so we use the<em> stoichiometric ratios</em> of the balanced reaction:
Thus 26.67 moles of HCl would react completely with 8.89 moles of Al(OH)₃.
Answer:
66.67%
Explanation:
From the given information:
mass of cyclohexane = 2.9949 grams
density of cyclohexane = 0.779 g/mL
Recall that:
Density = mass/volume
∴
Volume = mass/density
So, the volume of cyclohexane = 2.9949 g/ 0.779 g/mL
= 3.8445 mL
Also,
mass of propylbenzene = 1.6575 grams
density of propylbenzene = 0.862 g/mL
Volume of propylbenzene = 1.6575 g/ 0.862 g/mL
= 1.9229 mL
The volume % composition of cyclohexane from the mixture is:
= 66.67%
