Answer ————
60.8 g ammonia
Answer:
32.4 K
Explanation:
Initial pressure P1= 50.0mmHg
Initial temperature T1= 540K
Final temperature T2=????
Final pressure P2= 3 mmHg
From
P1/T1= P2/T2
P1T2= P2T1
T2= P2T1/P1
T2= 3×540/50.0= 1620/50.0
T2= 32.4 K
Answer:
The two constitutionally isomeric compounds that result from the reaction between sodium nitrite (NaNO2) and 2−Iodooctane are the following:
Answer:
P = 133.4 atm
Explanation:
Given data:
Mass of helium = 988 g
Volume = 45.0 L
Temperature = 23°C (23+273= 296 K)
Pressure of cylinder = ?
Solution:
Number of moles of helium:
Number of moles = mass/ molar mass
Number of moles = 988 g/ 4 g/mol
Number of moles = 247 mol
Pressure:
PV = nRT
P = nRT/V
P = 247 mol × 0.0821. atm. L/mol. K × 296 K / 45 L
P = 6002.5 / 45 L
P = 133.4 atm
