Question

calculate the number of moles in 92 g of soduim?​

Answer 1

Answer:

the number of moles in 92 grams of sodium is 4 mol

Explanation:

molecular mass for sodium = 23g/mol

mass of sodium = 92 g

Number of moles= (Molar mass of sodium)/(Mass of sodium)

⇒ number of moles = 23/92

=4 mol

Answer 2

Answer:

Given mass of sodium=92g

Molar mass=23g/mol

Number of moles=  

Molar  mass  of  sodium

Mass  of  sodium

⇒ number of moles =  

23

92

 =4 mol

Thus, the number of moles in 92 grams of sodium is 4 mol.
