Answer: Confidence, strength, potential
Explanation:
Answer:
The correct answer is option false.
Explanation:
Molality of the solution defined as moles of substance present in 1 kilogram of solvent.
Moles = 

Mass of percent (w/w%) of the solution is defined as amount of solute present in 100 grams of solution.

So, if want to inter-convert molality into mass percent we can do that without knowing density of solution.
Mass of solution = Mass of solute + Mass of solvent
Thank you for posting your question here. You just provide a situation, I assume below are the questions:
<span>1. What is the current in the heating element?
</span>
<span>2.What is the resistance of the dryer's heating element at its operating temperature?
</span>
Below are the answers:
1. <span>P = V∙I </span>
<span>I = P/V = 4100 W / 240 V = 17.08 A
</span>
2. <span>Ohm's law: </span>
<span>V = R∙I
</span><span>R = V/I = 240 V / 17.083 A = 14.05 Ω</span>
