Question

using identities, evaluate 2022​

Answer 1

Answer:

A conductivity cell with 0.05M NH4OH solution showed a resistance of 50 ohm at 298 K.If the cell constant is 0.50 cm -1 and molar conductance of NH4OH at infinite dilution is 47.4 ohm -1 cm2 mol -1

Answer 2

$2022 = (2000 + 22) \\ a = 2000 \: \: \: \: \: b = 22 \\ {(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab \\ = {(2000)}^{2} + {(22)}^{2} + 2 \times 2000 \times 22 \\ \\ = 4000000 + 484 + 88000 \\ = 4088484(answer) \\ \\ { \huge{ \red{ \ hope \: this \: helps \: u}}}$
