If the density of a solution is $3.12 \ g/mL$,the mass of $1.5 \ mL$ solution in significant figures is ............ $g$

Convert the following pressure values into atmosphere $(atm)$:
$(a)$ $735 \ torr$
$(b)$ $985 \ mbar$
$(c)$ $1.42 \times 10^5 \ Nm^{-2}$

The incorrect rule regarding the determination of significant figures is

$2 \times 10^{8}$ atoms of carbon are arranged side by side. Calculate the radius of a carbon atom if the length of this arrangement is $2.4 \, cm$.

How many significant figures are present in the following?
$(i)$ $0.0025$
$(ii)$ $208$
$(iii)$ $5005$
$(iv)$ $126.000$
$(v)$ $500.0$
$(vi)$ $2.0034$

Which of the following have the same number of significant figures?
$(A)$ $0.00253$
$(B)$ $1.0003$
$(C)$ $15.0$
$(D)$ $163$
