1. N2 + 2O2 → N2O4 a. If 15.0g of N2O4 was produced, how many moles of O2 were required? = 0.326 mol O2 b. If 4.0x10-3 moles of oxygen reacted, how many grams of N2 were needed? = 5.6x10-2 g N2 2. K3PO4 + Al(NO3)3 → 3KNO3 + AlPO4 a. What is the mass of potassium nitrate that is produced when 2.04 moles of potassium phosphate react? = 619g KNO3 b. a. 2.48 g of HBr. b. 4.77 g of CS 2. c. 1.89 g of NaOH. d. 1.46 g of SrC 2 O 4. 16. Decide whether each statement is true or false and explain your reasoning. There are more molecules in 0.5 mol of Cl 2 than in 0.5 mol of H 2. One mole of H 2 has 6.022 × 10 23 hydrogen atoms. The molecular mass of H 2 O is 18.0 amu. answer The only new concept we will introduce in this unit is the idea of a mole. A mole is a quantity of matter that we use for conversion purposes. We can convert from grams to moles, liters to moles (for gases), and atoms or molecules to moles. Title: Relative Mass and the Mole answer key Created Date: 20171005134609Z

Mole to Mole Problems KEY Worksheet: Mole/Mole Problems Name Answer each of the following questions using the equation provided. BE SURE TO BALANCE EACH EQUATION BEFORE SOLVING ANY PROBLEMS. SHOW ALL WORK. NO + 02 N02 1. How many moles of N - will be produced if 3.6moles NO react? 2. For CO 2 (m.w. = 44.01 u), mole CO 2 = 44.01 g CO 2 = 6.022 x 10 23 CO 2 molecules. Because each CO 2 molecule is composed of one carbon atom and two oxygen atoms, we could say that a mole of CO 2 contains one mole of carbon atoms and two moles of oxygen atoms. In general, it is useful to think of a mole as just an Avogadro's number of things. Moles Molecules and Grams Worksheet How many molecules are there in 24 grams of FeF3?
