A volume of 1 liter (cube with side length of 10cm) has the weight of one kilogram. One kilogram is 2.20462262 pounds.
specific gravity
Density is mass per unit volume, and sometimes in some industries weight per unit volume is used. Weight per unit volume is also sometimes called specific weight. Weight and mass are not the same. Volume per unit mass is called specific volume, and is the reciprocal of density. It is not clear whether volume per unit weight can also be used as a measure of specific volume.
hydrometer
The volume of a gas is not directly proportional to its molecular weight.
Density is Weight per Volume so you measure the weight of the brick using a scale and find the volume by multiplying length by width by height and then divide the weight by the volume.
A beam balance compares 2 weights. A physical balance compares a weight to a known referance (ie spring

Specific gravity compares the weight of a mineral with the weight of an equal amount of water! :D
Hardness compares the weight of a mineral with the weight of an equal amount of water
The density of minerals is a measure of weight vs volume of the mineral. See related links for more details.

Biomass
No. Vitamins and Minerals contain no energy or calories. Other factors in pregnancy make you gain weight, such as the weight of the baby, increased blood volume, and increased needs for food.

How much weight a boat will hold depends on the volume of the boat. This is called displacement. displacement is exactly equal to the weight of the water the boat displaces, that is the boat makes a hole in the water. The volume of that hole times the weight of water (64 lbs for salt water, 62.4 for fresh water) - displacement. The volume of water displaces is equal to the volume of the boat.
