It is always a whole number multiple of the empirical formula.", "Image ImageDescription": "In order to determine the molecular formula, you need to know the molar mass (usually determined through experimentation methods). For Example, hydrazine is a compound that contains nitrogen and hydrogen. Its empirical formula is NH2, but its molar mass is 32.0 g/mol. What is the true formula of hydrazine? How to solve this problem: Step 1: Determine the formula mass of the empirical formula. 1 N + 2 H = (2 x1.01) = 16.02g/ mol. Step 2: Divide the Molar mass by the empirical formula mass (efm). Round to the nearest whole number. This will give you the \u2018multiple\u2019 of the empirical formula g/mol \u00f7 g/mol = 1.99 = 2 (whole number)", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
