An ore of iron has the formula Fe3O4. What is the approximate percentage of iron in this ore?A:72B:42C:52D:62
Question
Solution 1
To calculate the percentage of iron in Fe3O4, we first need to find the molar mass of Fe3O4 and the molar mass of Fe.
Step 1: Calculate the molar mass of Fe3O4 The molar mass of Fe is approximately 55.845 g/mol and the molar mass of O is approximately 16.00 g/mol. So, the molar mass of Fe3O4 = (3 * Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
