  • M be molar concentration
  • V be volume

So

  • M1=0.845M
  • V1=200mL=0.2L
  • V2=0.6L
  • M2=?

\\ \tt\rightarrowtail M1V1=M2V2

\\ \tt\rightarrowtail 0.845(0.2)=0.6M2

\\ \tt\rightarrowtail 0.169=0.6M2

\\ \tt\rightarrowtail M2=0.281M

A 59.1 sample of aluminum is put into a calorimeter (see sketch at right) that contains of water. The aluminum sample starts off
Gemiola [76]

Answer:

Specific heat capacity of aluminium is 0,863 J/g°C

Explanation:

<em>Values: 250g of water, aluminum sample starts off at 91.3°C, water starts off at 16.0°C, temperature of the water stops changing it's 19.5°C</em>

In this problem, the heat produced for the aluminium is the same consumed by water. The heat consumed by water is:

Q = C×m×ΔT <em>(1)</em>

Where C is specific heat of water (4,184J/g°C), m is mass of water (250,0g) and ΔT is change in temperature of water (19,5°C-16,0°C = 3,5°C)

Replacing:

Q = 4,184J/g°C×250,0g×3,5°C

<em><u>Q = 3661 J</u></em>

Using (1), it is possible to obtain specific heat of aluminium, thus:

Q / (m×ΔT) = C

Where Q is heat (3661J), m is mass (59,1g) and ΔT is change in temperature (91,3°C - 19,5°C( = 71,8°C

Replacing:

3661J / (59,1g×71,8°C) = C

<em>C = 0,863 J/g°C</em>

I hope it helps!
