Then, find the mass of substance B: \(3.75 \, \text{moles} \times 93 \, \text{g/mol} = 348.75 \, \text{g}\).

["How to Calculate the Mass of Substance B: A Simple Guide", "When working with chemical substances, understanding how to calculate their mass is essential for laboratory accuracy and scientific experiments. A common calculation researchers perform is determining the mass of a substance based on the number of moles and its molar mass.", "In this guide, we focus on finding the mass of substance B using a straightforward formula:", "[\n\ ext{Mass} = \ ext{Number of Moles} \ imes \ ext{Molar Mass}\n]", "### The Calculation Explained", "Given the data:", "- Number of moles of substance B = 3.75 moles\n- Molar mass of substance B = 93 g/mol", "Applying the formula:", "[\n\ ext{Mass} = 3.75 , \ ext{moles} \ imes 93 , \ ext{g/mol} = 348.75 , \ ext{g}\n]", "### Why This Formula Works", "The molar mass (in grams per mole) represents the mass of one mole of a substance in grams. Multiplying the number of moles by the molar mass gives the total mass in grams. This conversion is fundamental in stoichiometry, chemical reactions, and quantitative analysis.", "### Practical Application", "This calculation is valuable in labs for preparing solutions, analyzing yields, or following safety and stoichiometric protocols. Knowing the precise mass ensures accurate mixing and reliable results.", "### Summary", "To find the mass of substance B:", "1. Identify the number of moles (3.75 mol)\n2. Use the molar mass (93 g/mol)\n3. Multiply: (3.75 \ imes 93 = 348.75 , \ ext{g})", "So, the mass of substance B is 348.75 grams.", "Mastering this method enhances your ability to conduct precise and reproducible chemistry work—key skills for students, chemists, and researchers.", "---", "For additional help with chemical mass calculations or unit conversions, explore detailed tutorials and practice examples to build confidence in your laboratory skills."]
