The conc of NaOH is 0.104M which means that 1000mL solution contains 0.104mol of NaOH, so the amount of moles used in the titration will be
The reaction of NaOH and HCl is one to one so the moles of HCl that were titrated will also be
The Molarity is therefore
B) as it is ionic, so has strong ionic bonds between molecules, but ions cant move so charge cant move through the material, meaning it can't conduct electricity very well
Answer: Option A. 0.820g/mL
Explanation:
Mass = 12.3 g
Volume = 15mL
Density = Mass /volume
Density = 12.3/15 = 0.82g/mL

Answer:
0.67 L
Explanation:
Given data:
Volume of carbon dioxide = ?
Mass of nitroglycerine = 2.5 g
Temperature = standard = 273.15 K
Pressure = standard = 1 atm
Solution:
Chemical equation:
4C₃H₅N₃O₉ → 12CO₂ + 10 H₂O + 6N₂ + O₂
Number of moles of nitroglycerine:
Number of moles = mass/ molar mass
Number of moles = 2.4 g/ 227.1 g/mol
Number of moles = 0.01 mol
Now we will compare the moles of nitroglycerine and carbon dioxide from balance chemical equation.
C₃H₅N₃O₉ : CO₂
4 : 12
0.01 : 12/4×0.01 = 0.03 mol
Volume of CO₂:
PV = nRT
V = nRT/P
V = 0.03 mol× 0.0821 atm.L/mol.K× 273.15 K / 1 atm
V = 0.67 L
