Question

Give three kinds of information conveyed by the formula $H_{2}O.$

Answer 1

Information conveyed by the formula ${\mathrm{H}}_2\mathrm{O}$

• $H_{2}O$ is the chemical formula of water having the density around 1 g/cm³.

$Density=\frac{mass}{volume}$

• The latent heat of vaporization (a liquid changed into steam) of water is 540 cal/g and the latent heat of freezing (a liquid changes into ice) of water is 80cal/g.
• At ${25}^{°}C$, the pH of pure water is 7 which is considered as neutral.
