Answer:

A. the accepted value for the density of aluminum

Explanation:

To know if your calculation is accurate or not, you need to know the accepted value. An example is if the accepted value was 15 and your calculation was 14.9, your calculation is accurate because its close to the actual value. If your calculation was 7, you would not be accurate at all because you are far from the actual value. Hope this helps please give brainliest!

The water bottle contains 575 grams of water at 80°C. The water eventually cools to

Jet001 [13]

Answer:

–23000 Calories.

NOTE : The negative sign indicates that heat has been loss to the student back.

Explanation:

The following data were obtained from the question:

Mass (M) of water = 575 g

Initial temperature (T1) = 80 °C

Final temperature (T2) = 40 °C

Heat (Q) transferred =.?

Next, we shall determine the change in temperature (ΔT).

This is illustrated below:

Initial temperature (T1) = 80 °C

Final temperature (T2) = 40 °C

Change in temperature (ΔT) =?

Change in temperature (ΔT) = T2 – T1

Change in temperature (ΔT) = 40 – 80

Change in temperature (ΔT) = –40°C

Finally, we shall determine the heat transferred. This can be obtained as follow:

Mass (M) of water = 575 g

Change in temperature (ΔT) = –40°C

Specific heat capacity (C) of water = 1 Cal/g°C

Heat (Q) transferred =.?

Q = MCΔT

Q = 575 × 1 × –40

Q = –23000 Calories

NOTE : The negative sign indicates that heat has been loss to the student back.

1718 l of a 0.3556-m c3h7oh solution is diluted to a concentration of 0.1222 m, what is the volume of the resulting solution

Agata [3.3K]

Answer : The volume of the resulting solution will be 0.4999 L.

Explanation : As the two molar concentration of the $C_{3} H_{7}OH$ solution are given and one of the volume concentration needs to be found.

So, according to the formula :- $m_{1}V_{1} = m_{2}V_{2}$

And here if we consider $V_{1}$ as 0.1718 L moles and $m_{1}$ as 0.3556 moles then we need to find $V_{2}$ as $m_{2}$ is given as 0.1222 moles.
Hence on solving the formula we get,

$V_{2}$ = (0.1718 X 0.3556) / 0.1222 = 0.4999 L
