Chemistry and measurement Chemistry can feel like learning a new language. Not only are you dealing with chemical formulas, but also often problem solving with unit conversions, dealing with significant figures in calculations. If we treat it like a new language, then perhaps we can allow for a more successful approach in learning it. Just […]
