Answer:
7. a] Atomic mass in terms of grams.
8. b] 2 mole of water.
9. b] 1 mole of C₆H₁₂O₆.
10. c] C₆H₆.
Explanation:
7. a] Atomic mass in terms of grams.
8. b] 2 mole of water.
H₂O = H = 1 amu + O = 16 amu
= [1 × 2] + 16
= 2+16 = 18
2 H₂O = 2 × 18 = 36 g.
9. b] 1 mole of C₆H₁₂O₆.
C = 12, H = 1, O = 16
C₆ H₁₂O₆ = 12 ˣ 6 + 1 ˣ 12 + 16 ˣ 6
= 180 g
10. c] C₆H₆.
HOPE YOU UNDERSTOOD!
PLEASE MARK AS BRAINLIEST!
