Read the Question! What do you want to know? What do you know? Are there any handy formulas? Which Formula? Do the Math Make sure the UNITS are correct
What do you want to Know? Read the question carefully, beware of distractors, Sometimes the question is in several steps, so it may be asking you several questions! – What are they?
What do you Know? In the question, it will give you certain information, Some information comes from outside (what you have learned, basic facts [atomic mass, gravitational force], or things you will have to look up. You might want to make a list of those things.. (some of those may be distractors!)
Are there any Handy Formula? There are often – in Physics and Chemistry – useful formulas!!! Make a list of the relevant ones for the problem. Have a list of all the formulas in your notebook!!!
Which Formula? Or do you have to modify it? If you memorize one basic one. eg. Molar Mass = g / Mole That means, algebraically you know: g = Moles x Molar Mass & Moles = g / Molar Mass
