A 0.4444 g of organic compound of unknown composition containing carbon, hydrogen and oxygen, is burned with oxygen, and produces 1.124 g of CO2 and 0.1822 g of H20. Calculate the mass of carbon, of hydrogen, and of oxygen that are contained in the organic compound. To obtain the exact answer, use the molar of C being equal to 12.01 g; the molar mass of H 1.010 g; the molar mass of O 16.00 g. In your answer, do not type in the unit gram, just type in the numbers that follow the rules of handling significant figures. Hint 1: Look up the example problem in the next, last question. Hint 2: Consider the law of mass conservation: the mass must be the same before and after a chemical reaction. The mass of carbon is g. The mass of hydrogen is g. The mass of oxygen is g.

This is stoichiometry And it’s for % yield

i need help for question (c) (ii) and (iii) , they are not graded questions they are for my revision :(( i'll be having my final exam for chemistry this wednesday please help

Determine the limiting reagent for the following reaction if 25.0 g of HC2H3O2 react with 25.0 g of NaHCO3. Also determine the theoretical yield of H2O for the reaction. HC2H3O2 + NaHCO3 -> NaC2H3O2 + CO2 + H2O Limiting reagent is  . Actual yield is  g.

Given the balanced equation, calculate the mass of product that can be prepared from 1.60g of zinc metal. 2Zn(s)+O2(g)-->2ZnO(s) Express your answer with the appropriate units.

Given the equation 2 NH3 -->  N2 + 3 H2, convert 5.25 mol N2 to moles of H2.  Round to the nearest 0.01, and remember to include units (properly abbreviated) and substance in your answer!

Enter the coefficients directly from the balanced chemical equation. Do not reduce to lowest terms. For example: If 3 moles H, react with 3 moles O, enter "3" for each, not "1". According to the following reaction: 4HCI (aq) + 0, (g) 2H20 (1) + 2Cl, (g) What would you multiply "grams of hydrochloric acid" by to convert to the units "moles of oxygen" ?
