Co molar mass









co molar mass

of moles of a gas that occupies a volume of 6 12. The mass of a gas that occupies a volume of 612.5 ml at room temperature and pressure (25☌ and 1 atm pressure) is 1.1g. So total amount of AgCl formed is 0.025 moles (based on the stoichiometry calculator)Īmount of AgCl present in 0.025 moles of AgCl Similarly, No of moles of KCl present in loo mL of 1.865% KCl solution of moles of AgNO 3 present in 50 mL of 8.5% AgNO 3 solution

co molar mass

What is the mass of precipitate formed when 50 ml of 8.5% solution of Ag NO 3 is mixed with 100 ml of 1.865% potassium chloride solution?ĥ0 mL of 8.5% solution contains 4.25 g of AgNO 3 (c) The ratio between the number of molecules in A to number of molecules in B is 2 : 1 (d) number of molecules in B is three times greater than the number of molecules in A (c) the ratio between the number of molecules in A to the number of molecules in B is 2 : 1 (b) number of molecules in B is more than that in A (a) number of molecules in A and B are the same Two 22.4 liter containers A and B contains 8 g of O 2 and 8 g of SO 2 respectively, at 273 K and 1 atm pressure, then ……….

(b) the ratio of elements to each other in a compound (a) the ratio of chemical species to each other in a balanced equation If Avogadro number were changed from 6.022 × 10 23 to 6.022 × 10 20, this would change ………. The equivalent mass of ferrous oxalate is ………. The correct increasing order of the oxidation state of sulphur in the anions SO 4 2-, SO 3 2-, S 2O 4 2-,S 2O 6 2- is ………. of electrons present in 0.1 mol of ammonia The weighted average atomic mass of the element X is closest to ………… Hence, option (a) is correctĪn element X has the following isotopic composition 200X = 90 %, 199X = 8 % and 202X = 2 %. Since the product was cooled to room temperature, water exists mostly as liquid. Finally, add the products together and you’ll arrive at the answer. Next, multiply the number of a particular element by its molar mass. In this compound, there are 1 C, 4 H (3+1), and 1 O. Volume of gas after cooling to the room temperature Start by determining how many of each elements there are by looking the subscripts (small number next to the element symbol). Volume of reactant reacted and product formed The volume of gas left after cooling to room temperature is ……….ĬH 4(g) + 2O 2(g) CO 2(g) + 2 H 2O (l) Content Tamilnadu Samacheer Kalvi 11th Chemistry Solutions Chapter 1 Basic Concepts of Chemistry and Chemical Calculations Samacheer Kalvi 11th Chemistry Chapter 1 Basic Concepts of Chemistry and Chemical Calculations Textual Evaluation SolvedĤ0 ml of methane is completely burnt using 80 ml of oxygen at room temperature.
