Your dad is working on creating a brick border for the lake in your backyard. each brick has a mass of 100 g and a volume of 20 cm3. what is the density of the brick? explain the steps you took to solve this problem, showing your work. then, explain if the brick will float or not if it falls in the lake. why or why not?

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
