In the second experiment, 4.20 g of chlorine reacted with 20.00 g of sodium, using up all the chlorine. 6.92 g of of sodium chloride was produced in the second experiment. Jun 07, 2008 · 24 grams C divided by 82 = 29% C. 3 grams H divided by 82 = 4% H. 32 grams O divided by 82 = 39% O. 23 grams Na = 28% Na. Added together they equal 100% of weight for sodium acetate. Given .87 moles, multiply the %'s by that part of a mole to see how many grams there are of each element. 29 (C) x .87 = 25 grams of carbon. 4 x l87 = 3.5 grams Ethane-13 C 2 /Helium Gas Mix. 1 Product Result | Match Criteria: Product Name, Property 577022 ; 99% 13 C, Helium 9, Ethane-13 C 2: Helium 1; Sigma-Aldrich In comparing a balloon containing 25 grams of helium to a balloon containing 25 grams of neon, which one of the following statements is TRUE?

One molecule of water (H 2 O) would weigh 18.02 amu (2×1.00797 amu for H + 15.9994 amu for O), and a mole of water molecules would weigh 18.02 grams. Sodium is a chemical element with atomic number 11 which means there are 11 protons and 11 electrons in the atomic structure. The chemical symbol for Sodium is Na. Sodium is a soft, silvery-white, highly reactive metal. The density of helium is equal to 0.1785 grams per liter. The density of air, on the other hand, is about 1.25 grams per liter. Leaving some tolerance for the weight of the balloon and the string, we can approximate that every liter of helium has a lifting force of one gram.
