Answer:
6.023*10 ²³ molecules
Explanation:
Moles is denoted by given mass divided by the molecular mass ,
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molecular mass .
From the question ,
given mass of NaCl = w = 58.5 g
As we know the molecular mass of NaCl = m = 58.5 g/mol
Moles can be calculted from the above formula -
n = w / m = 58.5 g / 58.5 g/mol = 1 mol
Since , 1 mol has 6.023*10 ²³ particles ,
Therefore ,
1 mol of NaCl = 6.023*10 ²³ molecules
Answer: 1 molecule
Explanation:
This is because the atomic mass of Na + Cl = 58.443.
