What is mol?
The measurement of amount of substance
Define as the number of 13C atoms in exactly 12 g of carbon-13
Three states of matter.
density, volume and weight
water, metal and gases

Matter is something that take up space and has mass.
Anything that has definite volume but no definite shape.
Density is a measure of how much mass is contained in a given unit volume.

6.022 x 1023 mol-1
The amount of entities per mole
1 mol Na = 23.0 g Na = 6.022 x 1023 Na atoms.
What is/are the correct relation between these units of volume?
1 L = 1 dm3
1 mL = 1 cm3
1 L = 1000 dm3
1000 mL = 100 cm3
Extensive properties depend upon the amount of substance in the sample.
Examples of intensive properties are
The temperature that is defined as standard temperature.
A form of matter having constant chemical composition and characteristic properties is known as
