Answer: A. There are two hydrogen atoms and one oxygen atom per water molecule.
Explanation:
The chemical formular for water "H2O", means it contain 2 hydrogen atoms and one oxygen atom per molecule.
For a normal boiling point of a liquid is 282 °C, the temperature is mathematically given as
T2=181.55°C\
<h3> What
temperature (in °C) would the
vapor pressure be 0.500 atm? </h3>
Generally, the equation for the gas is mathematically given as
ln(p1/p2)=dHvap/R(1/T2-1/T1)
Therefore
ln(1/0.26)=23500/8.214(1/T2-1/555)
T2=181.55^C
In conclusion
T2=181.55°C
