Hydrochloric acid is very corrosive. Handling it should be properly taken cared off. Personal protective equipment should be worn at all times when using this substance. PPE includes gloves specific for the substance used, goggles, closed flat shoes and laboratory gown. The same should be done for handling silver nitrate.<span />
Answer: 9.18 Litres
Standard Temperature and Pressure (STP). Think of this as the perfect environment where the Temp. is 0°C or 273 Kelvin and Pressure is always 1 atm. This is only true in STP.
This question uses the Ideal Gas Equation:
PV=nRT
P= 1 atm
V = ??
T = 273 K (always convert to Kelvin unless told otherwise)
n = 0.410 mol
R = 0.0821 L.atm/mol.K
What R constant to use depends on the units of the other values. (look at the attachments) The units cancel out and only Litres is left. You simply multiply the values.
Based on the concentrations given, the volume of vinegar required is 5.04 mL.
<h3>What is the concentration of the vinegar solution?</h3>
The concentration of a solution is the amount of solute in a given volume of solution.
Concentration can be expressed as:
- molar concentration
- percentage concentration
The concentration of the vinegar solution is 4.76% (w/w). This means that 4.76 g of vinegar is present in 100 g of solution.
Mass of vinegar = 4.76 g
molar mass if vinegar = 60 g/mol
moles of vinegar = 4.76/60 = 0.0793 moles
volume of solution/water = 100 mL or 0.1 L
Molarity of vinegar = 0.0793/0.1 = 0.793 M
1 mole of vinegar reacts with 1 mole of NaOH
let the volume of vinegar required be V
0.793 M × V = 40 × 0.1
V = 4/0.793
V = 5.04 mL
Therefore, the volume of vinegar require is 5.04 mL.
