## Is mercury a gas?

At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. If heated, it is a colorless, odorless gas.

## What is the mass of 1 mole of mercury?

200.59 g a) The atomic weight of mercury is 200.59, and so 1 mol Hg weighs 200.59 g.

## Why is a mole 6.022 x10 23?

The MOLE (mol) is a unit of measurement that is the amount of a pure substance containing the same number of chemical units (atoms, molecules etc.) as there are atoms in exactly 12 grams of carbon-12 (i.e., 6.022 X 1023).

## What is the molecular formula of c3h8?
