 Now, I'm going to show you how to measure the weight of a solid. In this case, I'm going to measure one gram of potassium chloride. So I want to make sure that I measure out from this container one gram of potassium chloride. I'm going to put this into this wane boat. So remember, we do not add or chemicals or salts or powders directly to the balance. We put them in either a wane boat or we use a whey paper. Today I'm going to use a whey boat. So again, in order to measure the mass of the solid, I have to measure the mass of the container that the solid is going to be in first. And then I'm going to measure the mass of the solid plus the whey boat in this case and then get the weight of my powder of my salt by subtracting the weight of the solid plus boat minus the weight of the whey boat itself. So before I put my whey boat on, I'm going to make sure I tear or zero the balance. Then I put my whey boat on and it's telling me that the mass of my whey boat is 2.22 grams. Then I'm going to use a spatula. This is a spatula that can be used to take all quantities of the salt from the container onto the whey boat. So I'm going to do that. So actually when I've added a gram, it's supposed to be 3.22 grams. That would give me the weight of the whey boat plus the salt. And I try to add the salt carefully so that I do not spill the salt over onto the whey boat. So if you notice, I'm way past the 3.22 mark. So I have to take out some of my salt. So because I don't want to put it back into my container, I will put the excess salt onto the skim wipe. And it's telling me it's 4.74. So if you notice, the volume keeps going down the more I take out. So it's at 3.75, or it's between 3.75 and 3.76 grams. So I take it out because I want it to be 3.22. So I take out some more. I'm getting there. So it's 3.15, so I gradually add a little bit from the spatula. So it's actually given me around the figure of 3.22 to 3.23 grams. So I have been able to measure one gram of solid of salt by actually measuring the whey boat first. And then the mass of the whey boat plus the salt is 3.22. So if I subtract the mass of the whey boat and the salt, so if I subtract the mass of my whey boat from the mass of the whey boat and the salt, I get one gram. So that is how you can use your pan, electronic pan in order to measure solid.
