Question

0.705 mole CH 2 (pentane) 5 56.7053.53 mol In solving problems involving chemical formulas, the number of grams of one substance cannot be compared directly to the number of grams of another substance; however, moles can be related to moles quite easily by looking at subscripts in chemical formulas. Use the map in Fig. 6.9 df your textbook to set up conversion factors, and use dimensional analysis to solve the problems below: a. How many moles of KCl would be found in 0.125 g of KCI? Imol = 1.68x1023 30.125 g x 14.55g b. How many molecules of KCl would be found in 0.125 g of KCI? c. Calculate the number of grams of Cl in 12.5 g of KCI. d. Calculate the number of fluorine atoms in 1.77 g of AlF3. e. Calculate the number of grams of F in 1.77 g of AlF3. 2016 Cengage Learning. All Rights Reserved.
