Note: moles to grams, or grams to moles you will need to use molar mass (g/mol).1)how many moles are in 20.2 g hcl? 2) how many grams are in 2 moles of hcl? note: when converting from moles to molecules, you need the following: 1 mole = 6.022 x 1023 molecules 3) how many molecules are in 23 moles of sodium? 4) how many moles are in 8.022 x 1026 molecules of nacl? note: 1 mole = 22.4 l 5) how many moles are in 5 liters of h2 gas? 6) how many liters are in 5 moles of h2 gas? multiple conversions in one problem. 7) how many grams of hcl will be produced with 16.2 grams of h2 and excess cl2? (h2 + cl2 -> 2hcl) 8) how many liters are there in 46 g of cl2 gas?

The first titration is done to standardize the silver nitrate solution. so first determine the number of moles of kcl used. then, use the chemical reaction kcl+agno3→agcl(s)+k++no3− to determine the moles of agno3 (notice the 1: 1 ratio). next, calculate the molarity of agno3 using the volume, 61.9 ml . the second titration is done to find the nacl content in the chip. since only 46.9 ml of agno3 was used in this titration, you must find the moles of agno3 in that volume. then, use the chemical reaction agno3+nacl→agcl(s)+na++no3− to determine the moles of nacl (notice the 1: 1 ratio). next, convert moles of nacl to grams using its molar mass. finally, take the mass of salt (which is for the given mass of filtrate), and scale it per serving.
