Answer:
2.77 mol/kg
Explanation:
Molality is a sort of concentration that indicates the moles of solute in 1kg of solvent. In this case our solvent is water and, if we consider water's density as 1g/mL, we determine that the mass of solvent is 750 g.
We convert the mass to kg → 750 g . 1kg /1000g = 0.750 kg
Our solute is the NaOH → 83 g.
We convert the mass to moles → 83 g . 1mol /40g = 2.075 mol
Molality (mol/kg) = 2.075 mol / 0.75kg = 2.77 m
Answer:
12CO2 (g) + 12H2O (l) ⇒ C12H24O12 (s) + 12O2
Explanation:
Start by comparing the moles of carbons on the left to number on the right. The number of moles on both side of the arrow should be the same.
