The atomic mass unit is defined as 1/12 of the mass of a carbon 12 atom, and 1 atomic mass unit has a mass of 1.6605 x 10⁻²⁴ g. It follows that one carbon atom has a mass of 12 x 1.6605 x 10⁻²⁴ and thus the number of carbon atoms in present in 12 g of carbon equal 12 / (12 x 1.6605 x 10⁻²⁴) which equals 6.02 x 10²³.True / False.

You have 125g of a certain seasoning and are told that it contains 76.0 g of salt what is the percentage of salt by mass in this seasoning

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
