How many atoms of carbon are present in 34. 5 g caffeine, Cg H10N4O2 ? A 1.08 x 1024 B 8.57 x 1023 2.09 x 1023 2.67 x 1025 E 4.83 x 1023

A. (see pic) B. When an electrolyte solution (such as NaCl) is added to ice, the ions have ____ with water molecules and thus ____ the ability of the water molecules to form a solid ice structure. C. Given that water's freezing pt is 0C and the fp depression constant is 1.86 Ckg/mol, calculate the fp depression for a 3.55 molal soln (moles/kg) of NaCl in water. Assume ideal behavior of the ions. D. Given that water's fp is 0C and fp depression constant is 1.86 Ckg/mol, calculate the fp depression for 3.55 molal solution for CaCl2 in water. Assume ideal behavior of the ions.

With correct sig figs

a) b) as per guidelines you can answer these two question because they are bits of the same question

An aqueous BSA* solution in the tube on the left is in equilibrium with pure water in the tube on the right. The membrane that separates the two solutions is only permeable to water. When salt is added to the pure water on the right, aqueous BSA pure water H,0 permeable membrane the water level on the right increases c. d. no change in the levels occur none of the choices а. b. the BSA solution level on the left increases If salt is added to water, the fugacity of the water а. increases с. remains the same b. decreases d. none of the choices

Match each definition or prompt with the correct term on the right. The term used for a [Choose ] solution where water is the solvent. Water is considered this, due for its [Choose ] ✪ ubiquity in solutions. Water can conduct [Choose] ✪ an electric current with these dissolved in solution On it's own, pure water has a virtually [Choose ] ◆ no ability to do this to an electric current. In a saltwater solution, the salt is [Choose ] considered this. Glucose and other [Choose ] covalent compounds (except acids) are consider this when acting as solutes, and unable to carry current. î î
