1) Solids have a fixed shape
The particles of solids are held into their positions and are only able to vibrate about fixed points. The strength of the bonding means that the particles have their own shape, which they retain, and do not take the form of the container they are in.
2) Solids may not flow
The molecules of liquids are able to slide past one another due to weaker bonds between particles. This allows the liquid to flow; whereas, this movement is not possible in solids so they cannot flow.
3) Solids may fracture
The fact that solids possess a rigid structure means that they have the ability to fracture. Although some are able to withstand more stress than others, all solids may break. This breakage occurs when the intermolecular bonds are mechanically broken. This is not possible in the case of liquids because such rigid intermolecular bonds do not exist.
We use the ideal gas equation in order to calculate the temperature of the system. It is expressed as follows:
PV=nRT
where P is pressure, V is volume, n is the number of moles, R is the universal gas constant and T is the temperature.
15 atm (.1 L) = 0.5 mol (0.08206 L-atm / mol-K) T
T = 36.56 K
Hope this answers the question. Have a nice day.
Answer:
The molarity of the solution is 1, 23 M.
Explanation:
We calculate the weight of 1 mol of NaCl from the atomic weights of each element of the periodic table. Then, we calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case NaCl) in 1000ml of solution (1 liter)
Weight 1 mol NaCl= Weight Na + Weight Cl= 23 g + 35, 5 g= 58, 5 g
58, 5 g-----1 mol NaCl
89,94 g ---------x= (89,94 g x 1 mol NaCl)/58, 5 g= 1,54 mol NaCl
1249 ml solution------ 1,54 mol NaCl
1000ml solution------x= (1000ml solutionx 1,54 mol NaCl)/1249 ml solution
x=1,23 mol NaCl---> The solution is 1, 23 molar (1,23 M)
