Will recieve medal! if 1.2 kilograms of rust form on a bridge in five days, what should be the rate of reaction in grams per hour? (recall that a bar over the number means that zero is significant.) 100(first zero has bar over it) g/hr 0.05 g/hr 0.010 g/hr 10(zero has bar over it) g/hr,

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth
