WebQ.1 The empirical formula of a compound is CH. Its molecular weight is 78. The molecular formula of the. compound will be. (A) C2H2 (B) C3H3 (C) C4H4 (D*) C6H6. Q.2 On analysis, a certain compound was found to contain iodine and oxygen in the ratio of 254 gm of iodine. (at.mass 127) and 80 gm oxygen (at. mass 16). WebOne formula unit of sodium sulfate contains two atoms of sodium, one atom of sulfur, and four atoms of oxygen. Each sodium atom has an average molar mass of 23 grams per mole. So two sodium atoms will have an average molar mass of 46 grams per mole. One sulfur atom has an average molar mass of 32 grams per mole.

Web23 sep. 2024 · 1 mol Al = 26.98 g Al. Prepare a concept map and use the proper conversion factor. Cancel units and calculate. 3.987molAl × 26.98gAl 1molAl = 107.6gAl. Think about your result. The calculated value makes sense because it is almost four times times the mass for 1 mole of aluminum. WebHomogeneous mixtures are also known as solutions, and solutions can contain components that are solids, liquids and/or gases.We often want to be able to quantify the amount of a species that is in the solution, which is called the concentration of that species. In this article, we'll look at how to describe solutions quantitatively, and discuss how that information … WebAs you already know how the grams to moles conversion work, find the number of moles: n = 5988 g / 18.015 g/mol = 332.4 mol.
