plzz give the question in English
To find the weight of the gas you need to find the number of moles of using ideal gas formula. Remember to change the temperature unit to Kelvin and the pressure to kpa or atm
PV=nRT
n= PV/RT
n= 699 mmHg* 0.1333kpa * 0.357 L/ 8.314 kpa*L / mol*K * (45 +273.15)K
n=<span>0.012 moles
</span>
weight= n * molecular weight
weght= 0.012 *92.448 g/mol= 1.109 grams
To determine the number of moles of the gas, we need to relate moles to pressure, temperature and volume. To simplify things, we assume the gas is ideal so we use the ideal gas equation PV=nRT.
PV = nRT
n = PV / RT
n = 3.5 (9.0) / 0.08205 (74+273.15)
n = 1.1059 mol
Answer:
The anions that can act as bases (conjugate bases of weak acids) have the capability to hydrolyse water and produce OH− ions. Cl−, Br−NO−3, SO2−4 are all conjugate bases of strong acids that don't have the capability to hydrolyse water and so they aren't basic.
