Bam added 8.91 g of CsCl to 34.29 mL of H2O. Calculate the concentration of Bam's solution in units of g solute/100 g solvent. MWCsCl= 168.36 g/mol

MWH2O= 18.015 g/mol

Density of water= 0.9975 g/mL

Higher temperature = molecules move around faster. and vice versa.

Reaction involved in present system is :   c12h22o11 + h2o → 2 c6h12o6the reaction system is obeying following rate law:   rate = k[c12h22o11]thus, it is a first order reaction.now, for 1st order reactionrate constant (k) =  given: initial conc. = 3.0 g, final conc. = 2.7 g, t = 2.5 h∴rate constant (k) =  ∴ k = 0.04215 h-1now, for 1st order reaction, half life = 0.693/k = 0.693/0.04215 = 16.4 hthus correct answer is option b
