Question

No of Moles 12 grams of MgSO4 please fast​

Answer 1

Atomic weight of MgSO4 = 120 GM

120 GM Mgso4 = 1 mole

12 GM Mgso4 = 12/120 = 0.1 mole

Answer 2

Answer:

Therefore the number of moles of MgSO₄ present in 12 grams of the compound is 0.1 .

Explanation:

It is given that the mass of MgSO₄ = 12 grams

The atomic mass of Mg = 24 $g/mol$

The atomic mass of S = 32 $g/mol$

The atomic mass of O = 16 $g/mol$

Therefore the molar mass of MgSO₄ = 24+32+(4×16)

                                                              = 120$g/mol$

To find the number of moles of MgSO₄ = $\frac{given mass of the compound}{molar mass of the compound}$ = $\frac{12}{120}$ = 0.1 mole

Therefore the number of moles of MgSO₄ present in 12 grams of the compound is 0.1 .
