# What length of mercury column will a gas at 0.650*atm support?

Nov 3, 2016

$1 \cdot a t m$ of pressure will support a column of mercury $760 \cdot m m$ high.

#### Explanation:

The use of mercury manometers, despite its risks, is still widespread in inorganic laboratories.

And thus $0.650 \cdot a t m \times 760 \cdot m m \cdot a t {m}^{-} 1$ $=$ ??*mm*Hg.
