Three samples (A, B, and C) of pure substance composed ofsodium, sulfur, and oxygen were isolated and purified. Elemental analyses showed that sample-A contained 1.62 g sodium, 1.13 g sulfur and 2.25 g oxygen; sample-B contains 1.60 g sodium,2.23 g sulfur, and 1.67 g oxygen; while sample-C contains 1.46 g sodium, 1.02 g sulfur, and 2.03 g oxygen. Determine whether A, B,and Care samples of the same or different compounds.
A sample contains one or more of the ions: aluminum, calcium, copper(II), iron(III); upon addition of NH3, after centrifuging, it looks like the picture shown below. For each metal put in the correct letter: P = definitely present, A = definitely absent, U = uncertain, can't tell if present or absent. aluminum = , calcium = , copper = , iron = .

i need ur help because I have a hard time to figure out,
A 12 year old male patient has been prescribed Gaviscon suspension 5 mL four times a day. Gaviscon suspension contains 3.1 mmol Na+/5 mL. The recommended daily allowance (RDA) of salt for the patient is 3 g, which is the equivalent to 1.2 g sodium per day. The atomic mass of sodium is 23. What percentage of the patient’s recommended daily salt allowance is contained in his total daily dose of Gaviscon suspension? Answer to the nearest whole number. units - %
