What are the similarities in how formula weight and molar mass are calculated? A) Formula weight and molar mass are both calculated by taking the individual atoms' masses in the formula, multiplying them by how many there are in the formula, and then adding the numbers together. B) Formula weight and molar mass are both calculated by taking the individual atoms' masses in the formula, multiplying them by how many there are in the formula, and then subtracting the numbers from each other. C) Formula weight and molar mass are both calculated by taking the individual atoms' masses in the formula, dividing them by how many there are in the formula, and then adding the numbers together. D) Formula weight and molar mass are both calculated by taking the individual atoms mass in the formula, dividing them by how
