Avagadros number states that 1 mol of any substance is made of 6.022 x 10²³ units.
1 mol of Cu is made of 6.022 x 10²³ atoms of Cu.
the molar mass of Cu is - 63.5 g/mol
63.5 g of Cu is made of 6.022 x 10²³ atoms of Cu
therefore 127.08 g of Cu contains - 6.022 x 10²³ atoms / 63.5 x 127.08
number of Cu atoms - 1.20 x 10²⁴ atoms of Cu
answer is 1) 1.20 x 10²⁴ atoms
Answer:
combine together as one group and you should get the answer
Explanation:
Answer:
In chemistry, the molar mass M is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance. The base SI unit for molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol.
Hope This Helps! Have A Nice Day!!
Avogadro's number is 6.022×1023 molecules. Scientists use it to discuss and compare large numbers. It is useful because substances in everyday quantities contain large numbers of atoms and molecules.
