Mass-mass, volume-volume, mass-volume, and mole-mole
Molar mass H₂O = 18.0 g/mol and O₂ = 32.0 g/mol
2 H₂O --------> O₂ + H₂
(2* 18.0 g ) H₂O ----------> 32 g O₂
72.0 g H₂O ----------------> ?
mass of O₂ = 72.0 * 32 / 36
mass of O₂ = 2304 / 36
= 64 g of O₂
hope this helps!
Answer:
The solution is given below
Explanation:
Heat, q= mc∆T
q= 125g x 4.18 J/g∙°C x (21.18x- 24.28) °C
q= -1619.75J
NEGATIVE SIGN INDICATES THAT HEAT IS ABSORBED.
Enthalpy Change, ∆H = 1619.75 7/ 10.5 g
= 154.26 J/g
No. of moles of KBr = Mass of KBr/ Molecular Weight of KBr
=10.5g/119gmol-1
=0.088 mol
∆H= 1619.75 J/ 0.088 mol
= 18.41 kJ/mol
