Answer: I hope this Help You!:)

<u>Mass</u> is simply the measure of the amount of matter in a body.

<u>Weight</u> Weight is the measure of the amount of force acting on a mass due to acceleration due to gravity.

<u></u>

<em><u>The mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define), whereas weight is the force exerted on an object by gravity. In other words, an object with a mass of 1.0 kilogram weighs approximately 9.81 newtons on the surface of the Earth, which is its mass multiplied by the gravitational field strength. The object's weight is less on Mars, where gravity is weaker, and more on Saturn, and very small in space when far from any significant source of gravity, but it always has the same mass.</u></em>

The answer would be: C.  160.3 J/mol*K 

To solve this question, you need to know the equation for Gibbs free energy formula. Entropy is expressed as delta S. The temperature would be expressed as T. Don't forget that temperature use Kelvin as unit, not Celsius

The formula would be:
G= H- T*S
130.5 kJ/mol= 178.3kJ/mol - (25+273.15K)*S
(298.15K)*S=178.3kJ/mol - 130.5 kJ/mol
S= (47.8kJ/mol)/ 298.15K=
S= 0.1603 kJ/mol*K= 160.3 J/mol*K        ------> 1kJ= 1000J

Answer:

The values associated with the term, standard state, in a thermochemical system are option c

Explanation:

Temperature: 0.00 °C; pressure: 1.000 standard atmosphere

Otherwise you can write 0°C as 273 K

1 atm as 1.01325 bar, or 1013 mbars

If 5.4 g of NaNO3 is dissolved in 350 mL of water, what is the molarity of the solution?
Aleonysh [2.5K]

Answer:

0.18 Moles

Explanation:

first you need to convert the 5.4g to moles using molar mass

(\frac{5.4g}{1})(\frac{1mol}{84.99g} )=\frac{5.4g}{84.99g} =0.0635mol NaNO_{3})

once you have that done you can use the molarity equation to get the answer

M=\frac{0.0635mol}{0.350ml} =0.181428

now you need to round to the correct sig fig which will give you the correct answer of 0.18moles
