1 mole ------------ 6.02 x 10²³ atoms
? moles ----------- 5.0 x 10²³ atoms

moles = 5.0 x 10²³ / 6.02 x 10²³

= 0.830 moles

hope this helps!

How many grams of water would require 2200 joules of heat to raise it’s temperature from 34 degrees Celsius to 100 degrees celsi
Arada [10]

Answer:

Mass, m = 7.97 grams

Explanation:

We have,

Initial temperature was 34 degrees Celsius

Heat produced in it is 100 calories of heat

The specific heat capacity of water is 4.18 J/g °C

The heat produced due to change in temperature is given by :

Q=mc(T_f-T_i)

m is mass of water in grams

m=\dfrac{Q}{c(T_f-T_i)}\\\\m=\dfrac{2200}{4.18\times (100-34)}\\\\m=7.97\ g

So, 7.97 grams of water is required to produce heat of 2200 joules.

Using stoichiometry, you predict that you should be able to use 314.0 g of Al to produce 1551 g of AlCi3. In your lab
Alex787 [66]

Answer:

90.26%

Explanation:

From the question given above, the following data were obtained:

Theoretical yield of AlCl₃ = 1551 g

Actual yield of AlCl₃ = 1400 g

Percentage yield =?

The percentage yield of the reaction can be obtained as follow:

Percentage yield = Actual yield / Theoretical yield × 100

Percentage yield = 1400 / 1551 × 100

Percentage yield = 140000 / 1551

Percentage yield = 90.26%

Thus, the percentage yield of the reaction is 90.26%
