Question
Solution 1
To solve this problem, we need to use the molar mass of K2Cr2O7, which is 294.185 g/mol.
Step 1: Convert the molar mass from g/mol to kg/mol. 1 g = 0.001 kg, so 294.185 g = 0.294185 kg.
Step 2: Multiply the given moles of K2Cr2O7 by the molar mass in kg to find the mass. Mass = moles * molar m Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
