Question 34 of 126

A bakelite beaker has volume capacity of $500cc$ at $30^{\circ}C$. When it is partially filled with ${V}_{m}$ volume (at $30^{\circ}C$) of mercury, it is found that the unfilled volume of the beaker remains constant as temperature is varied. If ${\gamma }_{\text{bester}}=6\times {10}^{-6}0^{\circ}{C}^{-1},$ where $\gamma$ is the coefficient of volume expansion, then ${V}_{m}$ (in $cc$ ) is close to $\ldots$
