Law of definite and multiple proportions What is an empirical formula

Law of definite proportions What does the law of definite proportions say? No matter the volume, every given compound will have equal percentages of the elements involved. This doesn’t change if the compound is found in nature or made in a lab. Realmajick.com Diabetesdailypost.com

Law of definite proportions What percent is sodium in sodium chloride by mass? Sodium is 22.989 AMU Chlorine is 35.453 AMU Total mass is 58.442 22.989/58.442 x 100= 39.336% What happens if you have 6.022 x 1023 molecules? Diyanapm.wordpress.com

Law of multiple proportions What is the law of multiple proportions? If 2 elements combine to form different compounds, the percentages will be different, but will represent whole number ratios of the elements involved. If you have carbon dioxide and carbon monoxide, you have carbon and oxygen, but they are together in different ratios. Wcti12.com Globalclimatescam.com

Law of multiple proportions What would the formulas be if there were two compounds with the following percentages? One has 42.85% carbon and 57.15% oxygen while the second has 27.27% carbon and 72.73% oxygen. % to mass Mass to moles Divide by small Multiply ‘til whole
