Answer: Option (3) is the correct answer.

Explanation:

A condition where a gas if held at high temperature and low pressure then it will behave like an ideal gas.

This is because at high temperature gases will have high kinetic energy. Therefore, they will be in rapid motion and forces of attraction between them will be minimum.

Also, at low pressure gases will not come closer to each other and thus molecules of gas will move freely. Hence, the gas will behave like an ideal gas.

Thus, we can conclude that under conditions of high temperature and low pressure carbon dioxide gas will behave most like an ideal gas.

An acid with molar mass 84.48 g/mol is titrated with 0.650 M KOH. What volume of KOH solution is needed to titrate 1.70 grams of

RSB [31]

Answer:

$V=0.0310L=3.10mL$

Explanation:

Hello.

In this case, since the acid is monoprotic and the KOH has one hydroxyl ion only, we can see that at the equivalence point the moles of both of them are the same:

$n_{acid}=n_{KOH}$

Thus, since we are given 1.70 g of the acid, we compute the moles of acid that were titrated:

$n_{acid}=1.70g*\frac{1mol}{84.48g}=0.0201mol$

Which equal the moles of KOH. In such a way, since the molarity is defined as moles over liters (M=n/V), the liters are moles over molarity (V=n/M), thus, the resulting volume is:

$V=\frac{0.0201mol}{0.650mol/L}\\\\V=0.0310L=3.10mL$
