Which of the following is the mass in grams of 4.25 × 10³ mol …
WebDec 13, 2024 · This means that: molar mass of N2 = 2*14 = 28 grams. Now, number of moles can be calculated using the following rule: number of moles = mass / molar mass. Therefore: mass = number of moles * molar mass. mass = 4.25*10^3 * 28. mass = 119 * 10^3 grams. Advertisement. WebFeb 10, 2024 · Explanation: First, find the mass of N2. On the periodic table, nitrogen is 14.007. Because there are two nitrogens, multiply it by 2. 14.007*2 = 28.014 g. Now convert... (also don't let that exponent intimidate you! You can change it to 4250 if that makes it easier) 4.25 × 10³ mol * 28.014 g/1 mol = 119059.5 g/mol. Advertisement. how much are inheritance taxes in tx
