Question
How many grams of glucose (C₆Hâ‚â‚‚O₆, Molar Mass = 180 g/mol) are needed to prepare 0.5M solution in 1L water?
Explanation
90g is obtained by applying the relevant formula or quantitative relationship to the given parameters. In Water and Mole Concept, numerical problem-solving requires understanding the mathematical relationships between biological variables. The calculation involves substituting the provided values into the appropriate equation and solving systematically. The other options (180g, 45g, and 360g) result from common calculation errors such as using incorrect formulas, misidentifying variables, inverting ratios, or making arithmetic mistakes.
