Explicación:
1) 230 g de H2O a mol
H2 { H = 1 ×2 = 2
O { O= 16×1= 16
----------
18 g / mol
× = 1 mol × 230 g H2O
-----------------------------
18 gramos H2O
= 28.75 moles de H2O
2) 0.0071 moles de MgO
Mg { 24×1 = 24
O { 16 ×1 = 16
---------------
40 g / mol
0.0071 mol MgO × 40 g MgO
---------------------
1 mol MgO
= 0.284 gramos MgO
3) 1.98 moles de Fe a gramos
Fe { 55×1 = 55
--------------
55 g / mol
1.98 mol Fe × 55 g Fe
------------------
1 mol Fe
= 108.9 gramos Fe
espero te ayude :3
