answer: 2 mol
- according to the ideal gas law, one mole of an ideal gas at stp (standard temperature and normal pressure) occupies 22.4 liters.
- using cross multiplication,
1 mol of (o2) → 22.4 l
? → 43.9 l
therefore, the number of moles of oxygen in 43.9 l = (43.9 × 1)/ 22.4 = 1.96 mol≈ 2 mol..
hello, and yes i believe the correct answer is c.
hope this .
yes: 175 pm
the c-cl bond length varies slightly from one compound to another.
on average, it is about 176 pm.
in ccl₄, all c-cl bond lengths are identical at 175 pm.
a) 3.4 mole of h₂so₄.
explanation:from the stichiometry of the reaction: 2 lioh + h₂so₄ → li₂so₄ + 2 h₂oit is clear that 2.0 moles of lioh reacts with 1.0 mole of h₂so₄ to produce 1.0 mole of li₂so₄ and 2.0 moles of h₂o.
using cross multiplication:
1.0 mole of h₂so₄ reacts completely with → 2.0 moles of lioh
mole of h₂so₄ are needed to react completely with → 6.8 moles of liohthe number of moles of h₂so₄ = (1.0 x 6.8) / (2.0) = 3.4 mole of h₂so₄.
