State True or False for the following statements:
$(i)$ The volume of $N_2$ is measured by nitrometer.
$(ii)$ The weight of $N_2$ is measured by nitrometer.
$(iii)$ The weight of $NH_3$ is measured by nitrometer.
$(iv)$ The volume of $NH_3$ is measured by nitrometer.
$(i)$ The volume of $N_2$ is measured by nitrometer.
$(ii)$ The weight of $N_2$ is measured by nitrometer.
$(iii)$ The weight of $NH_3$ is measured by nitrometer.
$(iv)$ The volume of $NH_3$ is measured by nitrometer.
(A) The nitrometer is an apparatus used for the collection and measurement of gases,specifically used in the Dumas method for the estimation of nitrogen.
$(i)$ True: The volume of $N_2$ gas is collected and measured in the nitrometer.
$(ii)$ False: The nitrometer measures the volume of $N_2$,not its weight.
$(iii)$ False: The nitrometer is not used to measure the weight of $NH_3$.
$(iv)$ False: The nitrometer is not used to measure the volume of $NH_3$ in this context.
Therefore,the correct sequence is: $(i-T, ii-F, iii-F, iv-F)$.
$(i)$ True: The volume of $N_2$ gas is collected and measured in the nitrometer.
$(ii)$ False: The nitrometer measures the volume of $N_2$,not its weight.
$(iii)$ False: The nitrometer is not used to measure the weight of $NH_3$.
$(iv)$ False: The nitrometer is not used to measure the volume of $NH_3$ in this context.
Therefore,the correct sequence is: $(i-T, ii-F, iii-F, iv-F)$.
