Consider the following thermochemical equation:
Arisa [49]

Answer:

m_w=5.3248\times 10^{23}\ kg

Explanation:

According to the given reaction,

heat released by thecombustion of 2 molecules of Methanol, \Delta H=1277000\ J

we know that molecular mass of Methanol, m=32\ g.mol^{-1}

∴12 gram of methanol = \frac{3}{8}\ moles

we know 1 mole = 6.023\times 10^{23}\ molecules

so,

\rm \frac{3}{8} \ moles=2.258\times 10^{23}\ molecules

Heat from the combustion of 2.258\times 10^{23}\ molecules:

Q=1277000\times \frac{2.258\times 10^{23}}{2}

Q=1442132.0625\times 10^{23}\ J

<u>Now the  mass of water that can be heated from 23.5°C to 88.2°C :</u>

Q=m_w.c_w.\Delta T

1442132.0625\times 10^{23}=m_w.4186\times (88.2-23.5)

m_w=5.3248\times 10^{23}\ kg
