Answer:
The temperature in Celsius is 383, 7°C
Explanation:
We use the formula PV=nRT. We convert the pressure in KPa into atm:
101,325kPa---1 atm
114kPa--------x=(114kPa x 1 atm)/101,325kPa=1, 125 atm
PV=nRT ---> T= PV/nR
T=1, 125 atm x 35, 9 L/ 0,750 mol x 0,082 l atm/K mol
T= 656, 7 K
0°C= 273K---> 656,7 -273K= <em>383,7°C</em>

Answer:
mix 1 mL of the stock solution of MgCl2, 300 mL of the stock solution of NaCl and 699 mL of water.
Explanation:
We need to determine the volume necessary of both stock solutions. When a dilution is made, a certain volume of the stock solution is collected and then more solvent is added to it until the volume is completed. So, the number of moles of the solute in both solutions are the same, and it is the concentration (C) multiplied by the volume (V). If 1 is the stock solution and 2 the diluted solution:
C1*V1 = C2*V2
So, in this case, the two solutions will be mixed, and then the volume will be completed with the solvent. So, for MgCl2:
C1 = 1.0 M
C2 = 1.0 mM = 0.001 M
V2 = 1.0 L = 1000 mL
1*V1 = 0.001*1000
V1 = 1 mL of the stock solution of MgCl2
For NaCl:
C1 = 0.50 M
C2 = 0.15 M
V2 = 1000 mL
0.50*V1 = 0.15*1000
V1 = 300 mL
So, it will be necessary 1 mL of the stock solution of MgCl2, 300 mL of the stock solution of NaCl and 699 mL of water.
