Answer:

0.168M

Explanation:

We obtained the following information from the question:

C1 = 0.839 M

V1 = 500mL = 500/1000 = 0.5L

C2 =?

V2 = 2.5L

Using the dilution formula, we can obtain the concentration of the diluted solution as follows:

C1V1 = C2V2

0.839 x 0.5 = C2 x 2.5

Divide both side by 2.5

C2 = (0.839 x 0.5) /2.5

C2 = 0.168M the concentration of the diluted solution is 0.168M

The mass of water in a single popcorn kernel was found to be 0.905 grams after it popped at a temperature of 175 °C. Using the i
Rus_ich [418]

Answer:

0.583 kilojoules

Explanation:

The amount of heat required to pop a single kernel can be calculated using the formula as follows:

Q = m × c × ∆T

Where;

Q = amount of heat (J)

m = mass of water (g)

c = specific heat capacity of water (4.184 J/g°C)

∆T = change in temperature

From the given information, m = 0.905 g, initial temperature (room temperature) = 21°C , final temperature = 175°C, Q = ?

Q = m × c × ∆T

Q = 0.905 × 4.184 × (175°C - 21°C)

Q = 3.786 × 154

Q = 583.044 Joules

In kilojoules i.e. we divide by 1000, the amount of heat is:

= 583.04/1000

= 0.583 kilojoules
