Calculate the molarity of 0.700 mol of na2s in 1.05 l of solution.
slamgirl [31]
Molarity is the amount of solute molecule (in moles) per 1L of solvent. In this case, the solute is 0.7mol Na2S and the solvent volume is 1.05L. Since the unit in this problem is already mol and L then you don't need to do any conversion of the units. The calculation would be:

molarity = mol of solute / (1L/ volume of solvent)
molarity = 0.7 mol/ (1L/ 1.05L)= 0.67M

Use the van der Waals equation and the ideal gas equation to calculate the pressure for 1.50 mol He gas in a 1.00 L container at
Tamiku [17]

The difference in pressure is <u>8.98 %.</u>

What is pressure ?

In the physical sciences, pressure is defined as the stress at a point within a confined fluid or the perpendicular force per unit area. A 42-pound box with a bottom area of 84 square inches will impose pressure on a surface equal to the force divided by the area it is applied to, or half a pound per square inch. Atmospheric pressure, which is roughly 15 pounds per square inch at sea level, is the weight of the atmosphere pressing down on each unit area of the Earth's surface. Pascals are used to express pressure in SI units; one pascal is equivalent to one newton per square meter. Almost 100,000 pascals of atmospheric pressure are present.

Umnica [9.8K]
Potential energy<span> is the </span>energy<span> that is stored in an object due to its position relative to some zero position.  It is calculated by the expression as follows:

PE = mgh
PE = 25 (9.8) (3)
PE = 735 J

Hope this answers the question. Have a nice day.</span>
