V=2.90 L
c=1.8 mol/L
n(NaOH)=vc
n(NaOH)=2.90L*1.8mol/L=5.22 mol
Higher and lower temperatures
Water, because electrolysis is using electricity to break the bond of water to release 2 Hydrogens and the 1 Oxygen.
Answer:
Sample C has the highest density
Explanation:
Step 1: data given
Sample A has a mass of 224.96 grams
Sample B has a mass of 0.55632 lbs = 252.3425 grams
Sample C has a mass of 0.30648 kg = 306.48 grams
The volume is for all the sample equal
Step 2: Calculate density
We suppose the volume is 1000 mL
Density = mass / volume
Density sample A = 224.96 grams / 1000 mL = 0.22496 g/mL
Density sample B = 252.3425 grams / 1000 mL = 0.2523425 g/mL
Density sample C = 306.48 grams / 1000 mL = 0.30648 g/mL
Sample C has the highest density
