Stainless steel is an alloy of iron, chromium and nickel.
Answer:
Boiling point of the solution is 100.78°C
Explanation:
This is about colligative properties.
First of all, we need to calculate molality from the freezing point depression.
ΔT = Kf . m . i
As the solute is nonelectrolyte, i = 1
0°C - (-2.79°C) = 1.86 °C/m . m . 1
2.79°C / 1.86 m/°C = 1.5 m
Now, we go to the boiling point elevation
ΔT = Kb . m . i
Final T° - 100°C = 0.52 °C/m . 1.5m . 1
Final T° = 0.52 °C/m . 1.5m . 1 + 100°C → 100.78°C
Answer:
After the ejection of an alpha particle, the remaining nucleus has a mass number that is four less and an atomic number that is two less, so alpha decay is a type of nuclear fission.
The number of micrograms of contaminant each person will receive is 5,742.64 ug.
<h3>
Number of micrograms of contaminant per person</h3>
The number of micrograms of contaminant each person will receive is calculated as follows;
Amount of contaminant (mg) = (1.01 x 10⁻⁴ mg/mL) x 2.28 x 10⁴ L
Amount of contaminant (mg) = 2.3028 mg.L/mL
Amount of contaminant (mg) = (2.3028 mg.L/mL) x (1000 mL/L) = 2,302.8 mg
Amount of contaminant (ug) = 2,302.8 mg x 1000 ug/mg = 2,302,800 ug
<h3>Amount of contaminant per person (ug/person) </h3>
= (2,302,800 ug) / (401 persons)
= 5,742.64 ug per person
