Answer:

[tex]c=2.14J\text{/g}^0C[/tex]

Explanations

The formula for calculating the amount of heat energy absorbed is given as:

[tex]Q=mc\triangle t[/tex]

Given the following

• mass m = 50.0g

,

• Heat energy Q = 7490 Joules

,

• change in temperature = 80 -10= 70 degrees celsius

Substitute

[tex]\begin{gathered} 7490=50\times c\times70 \\ c=\frac{7490}{3500} \\ c=2.14J\text{/}g^oC \end{gathered}[/tex]

Hence the specific heat capacity of methanol is 2.14J/gC
