Question

calculate the number of moles in 60 gram of magnesium​

Answer 1

Answer: THE ANSWER IS 1.5

Explanation:

Firstly,

Calculate the molecular mass of NaOH i.e. 23+16+1=40g

Now,just apply formula for moles which is given mass/molar mass

Since,given mass is 60 ….apply the value

So, Moles = 60/40 = 1.5

Answer 2

2.47 moles

Explanation:

Formula:

$Number\, of Moles=\frac{Gram\, weight}{Gram\, Molecular\, weight}$

• Weight of Magnesium = 60 g

• Molecular weight of Magnesium = 24.305 g

• Therefore, Number of moles =  $\frac{60}{24.305}$

                                                        = 2.47 moles

• Thus the number of moles in 60 grams of magnesium = 2.47 moles
