What is the best way to know how to solve any problem for chemistry?
Hi, I m sorry for bugging, I m having a hard time solving chem problems; and it s only the math part. I m struggling with problems exactly like these:
• "Consider the limiting reactnt, how many mols of C are producd from the reactnt of 0.15 mol A and 2.20 mol B?"
• "If 20.0mL of 0.100 M HCl is titratd with 0.200 M NaOH, what vol of sodiun hydroxide solution is requird to neutralize acid?"
• "0.100g of sodium reacts to yield 0.400g of sodium oxide. Using consrvation of mass law, predct mass of reacting oxygen gas."
• "What is the mass of mercuric oxide (216.59 g/mol) that releases 0.375 L of oxygen gas at STP?"
• "What is the mass of silver metal producd frm 6.350g of magnesium?"
• "If 10.0 mL of 0.100 M Ca (OH)2 is titratd with 0.200 M HC2H3O2, what vol of acetic acid is requird to neutralize base?"
• "What is molarity of hydrochloric acid soln if 10.00mL of HCl is requird to neutralize 0.212g sodium carbonate (MM Na2CO3 is 105.99g/mol)?"
• "What is the percentage of water in CuSO4•5H2O?"
I want to know how to do them all without struggling. Is there one formula for each type of problem? I m sure it s simple to understand. I m probably just over thinking it. I know some say that no question is stupid, but I feel that, since I m having a hard time with chem, all questions I ask, is a stupid question. Will you please help me? I want to do well, and I m willing to do whatever it takes. Please, thank you so, so much for your time!
