Question

Please show me how to solve this.

A sample of 0.050mol of NH_3 gas had a volume of 300mL. The temperature and pressure were held constant and some ammonia was removed to reduce the volume to 150mL. How many g of NH_3 were removed? (Molar mass of NH_3 = 17.03g/mol) Which of the following statements is TRUE? As pH goes up H_3O^+ concentration goes down The pH of a 0.1M HCl solution is 0.1. A weaker acid dissociates more than a stronger acid OH_- is a Bronsted-Lowry acid Which of the following will have the weakest conjugate base? Explain your choice HSO_4^-, K_a= 1.2 times 10^-2 HCN, K_a= 4.9 times10^-10 HF,K_a = 7.2 times 10^-4 NH_4^+, K_a = 5.6 times l0^-10 Please show me how to solve this.

Explanation / Answer

18 as T & P constant Volume directly proportionalto mole. Henece 0.025 mole or 0.4257 g NH3 removed

.19 a

the larger the Ka the more stable the conjugate base as the reaction is faster hence the weakest one is the NH4+
