A metal oxide contains $60\%$ metal (by mass). The equivalent weight of metal is

In a hydrocarbon, mass ratio of hydrogen and carbon is $1:3$  the empirical formula of hydrocarbon is 

One mole of ${\mathrm{H}}_2\mathrm{O}$ corresponds to

The volume of $0.5 \mathrm{mol}$ of gas at $1 \mathrm{atm}$ pressure and $273 \mathrm{K}$ temperature is

Give the empirical formula of acetic acid $\left({\mathrm{CH}}_3\mathrm{COOH}\right)$.

By combining Boyle's law, Charles' law, and Avogadro's law an equation can be derived that gives the simultaneous effect of the change of pressure and temperature on the volume of the gas. This is known as ideal gas equation. The number of moles of ${\mathrm{H}}_2$ in $0.224 \mathrm{L}$ of hydrogen gas at $\mathrm{STP} (273 \mathrm{K}, 1 \mathrm{atm})$ assuming ideal gas behaviour is

By combining Boyle's law, Charles' law, and Avogadro's law an equation can be derived that gives the simultaneous effect of the change of pressure and temperature on the volume of the gas. This is known as ideal gas equation.The following graph illustrates

By combining Boyle's law, Charles' law, and Avogadro's law an equation can be derived that gives the simultaneous effect of the change of pressure and temperature on the volume of the gas. This is known as ideal gas equation. Plot of $\mathrm{P} \mathrm{vs} \frac{1}{\mathrm{V}}$ of a gas at different temperature is given as

The correct order of temperature ${\mathrm{T}}_1, {\mathrm{T}}_2$ and ${\mathrm{T}}_3$ is
