WebTo find the number of atoms in H2SO4 we’ll add up the number of atoms for H, S, and O. The small number after the element symbol is called the subscript and this tells us how many of that atom... WebExplanation of the correct answer: The correct answer is option C: From the given, 98 % by weight H 2 SO 4 = 98 gH 2 SO 4 100 g solution Volume of 100 g solution = mass density = 100 1. 8 = 55. 55 mL For 0.1 M, 9.8 g of H 2 SO 4 is needed. 55. 55 mL acid = 98 g 5. 55 ml acid = 9. 8 g = 0. 1 Molar acid Hence, option C is correct, i.e., 5.55 mL.

Web1. Which statement describes the structure of an atom? The nucleus has a positive charge and is surrounded by negatively charged electrons. 2. Which term is defined as the region in an atom where an electron is most likely to be located? orbital 3. What is the number of electrons in an atom of scandium? 21 4. Which particle has the least mass? WebJun 8, 2016 · We start with the units that we want to end up with and we set that equal to our given value, which will be multiplied by a conversion factor (the molar ratio from the balanced chemical equation). The #98.08g/(mol)# represents the molar mass of sulfuric acid and the #40.0 g/(mol)# is the molar mass of sodium hydroxide. So, what we have is: nantahala weddings events
