Increased Evaporation/B is correct :p
Answer: 0.02 molecules
The mass of sodium chloride= 23+35.5 = 58.5g
No. Of moles= Molar mass of NaCI
1.17 divided by 58.5 = 0.02
Answer:
0.45M
Explanation:
The following were obtained from the question:
C1 = 0.75M
V1 = 100mL
V2 = 165mL
C2 =?
Applying the dilution formula C1V1 = C2V2, the concentration of the diluted solution can be calculated for as follows:
0.75 x 100 = C2 x 165
Divide both side by 165
C2 = (0.75 x 100) /165
C2 = 0.45M
The concentration of the diluted solution is 0.45M
The approximate eutectoid temperature of this alloy that has 6.0 wt% Mn is 650°C or 1330°F.
<h3>How to calculate the temperature?</h3>
From the information given, the approximate eutectoid temperature of this alloy that has 6.0 wt% Mn is 650°C. This can be converted to Fahrenheit as:
= (650 × 2) + 30
= 1300 + 30
= 1330F
The proeutectoid phase when this alloy is cooled to a temperature just below the eutectoid will be ferrite. It's a ceramic like material with magnetic properties.
The relative amounts of the proeutectoid phase will be:
= (0.62 - 0.20)/062
= 0.68
Similarly, the relative amount of the pearlite will be:
= 0.20/0.62
= 0.32
