How do chemists weigh and count particles of matter?
Answers
Answer:
Counting by Weighing
Counting by weighing is one of the most efficient ways of counting large numbers of objects. Suppose that you have a job packing 1,000 nuts and 1,000 bolts in big bags, and you get paid for each bag you fill. So what’s the most efficient and quickest way of counting out nuts and bolts? Weigh out a hundred, or even ten, of each and then figure out how much a thousand of each will weigh. Fill up the bag with nuts until it weighs the amount you figured for 1,000 nuts. After you have the correct amount of nuts, use the same process to fill the bag with bolts.
In chemistry, you count very large numbers of particles, such as atoms and molecules. To count them efficiently and quickly, you use the count-by-weighing method, which means you need to know how much individual atoms and molecules weigh. Here’s where you find the weights:
✓ Atoms: Get the weights of the individual atoms on the periodic table — just find the atomic mass number.
✓ Compounds: Simply add together the weights of the individual atoms in the compound to figure the molecular weight or formula weight. (Note: Molecular weights refer to covalently bonded compounds, and formula weights refer to both ionic and covalent compounds.
Answer:
chemists weight and count the no. particles of matter by a unit called as mole.
mole is a collection of 6.022 into 10 ^ 23 particles which may be atoms ,molecules and ions of any substance.
