Answer:
1.
Fe- 55g×1 mol= 55g/mol
S-32g×1 mol= 32g/mol
O2-16g×2 mol =32g/mol
55+32+32= 119g/mol
Fe:
55g/mol
-------------- ×100
119g//mol
55÷119 = 0.4
0.4×100= 40
Answer: 40
S:
32g/mol
------------- × 100
119 g/mol
32÷ 119 =0.2
0.2×100=20
Answer: 20
O:
32g/mol
------------- × 100
119g/mol
32÷119= 0.2
0.2×100
Answer: 20
maya ko po sagutan ung iba may klase kasi kami tenchu
