It well be 9025 because it will dissolve in 0.8 hcl soluiton
Answer:
OH
Explanation:
Hydroxide is a diatomic anion with chemical formula OH⁻.
The empirical formula CH₂O has a mass [(12 × 1) + (1 × 2) + (16 × 1)] = 30 g/mol
If the empirical formula is 30 g/mol,
and the molecular formula is 60 g/mol
Then the multiple is = 60 g/mol ÷ 30 g/mol
= 2
Therefor the molecular formula is 2(CH₂O) = C₂H₄O₂ (OPTION 2)
Answer:
.24 mol / liters
Explanation:
38. 2 ml = .0382 liters
.0382 liters times ( 0. 163 m KOH/1 liter) times ( 1 mol H2SO4/ 1 mol koh) =
.006/.025 liters = .24 mol / liters
