The mass of KCl per volume of solution=.35X(35.5+39)=26.075g/L
Answer:
The statement is true.
Explanation:
&he pressure exerted by a liquid depends on the height of the liquid column. Where h is height and ρ is density. As the height increases, pressure will also increase.
To convert on unit to another unit, a conversion factor is needed to multiply in the value given. For the value given above, we have to convert it from miles per gallon to kilometers per liter. The factors to be used are:
1 mile = 1.61 kilometers;
1 gallon = 3.79 liters.
<span>34.0 miles / gallon ( 1.61 kilometers / 1 mile ) ( 1 gallon / 3.79 L ) = 14.44 kilometer / liter</span>
Hvap, Tvap, Mr are constants
Hvap = 443.38 kJ/kg = 196417.34 J/mol
Tvap = -85.1 °C
Mr = 36.5 g/mol
n = 1.80 mol
ΔS = n*Hvap/Tvap
ΔS = 1.80 * 196417.34 / (273-85.1)
ΔS = 1881.59 J/K = 1.882 kJ/K
Answer:
the major difference between electricity and magnetism is it presence of magnetism and electricity give you present in a static charge of magnetism president is only felt when they are moving charge as a result of electricity
