A sample of O2, under occupies 500ml at 25.0°C. What volume will the sample occupy at 0.0°C

NeX [460]

Answer:

458ml

Explanation:

According to charles law, $\frac{V_{1}}{T_{1}} =\frac{V_{2}}{T_{2}}$

Given values,

Volume occupied $V_{2}=500ml$

Temperature $T_{1}=25.0^{\circ}C=25+273=298K$

Second temperature $T_{2}=0.0^{\circ}C=273K$

Volume $V_{2}=?$

From charles law, $V_{2}=\frac{V_{1} \times T_{2}}{T_{1}}$ \\$=\frac{500 \times 273}{298}$\\$=458ml$

$\therefore$ Volume occupied by the oxygen at 0.0°C is 458ml

Hi:) anyone able to explain the last column? Thanks !!

RUDIKE [14]

I'll try to explain this in the simplest way I've learned it.

What the last column basically meant was that if the second word of the compound has a negative ion charge

and contains oxygen it will give the the compound a name ending with -ate
