Answer: Lithium (Li) 16.373%
Chlorine (Cl) 83.627%
Explanation:
Zinc (ii) sulfate heptahydrate has a formula of ZnSO4.7H2O
Therefore, note that one mole of ZnSO4.7H2O, contains 7 moles of H2O,
Hence, 3.8 moles of ZnSO4.7H2O will contain;
3.8 × 7/1
= 26.6 moles of H2O
Answer:
232 g CO2
2 C8H18 + 25 O2 --> 16 CO2 + 18 H2O
75.3 g C8H18 (1mol / 114.26g) (16 mol CO2/2 mol C8H18) (44.01 g/1 mol) = 232 g
Hope this helps!
