Soil pH can be determined by different methods such as, 1) Saturation Soil Paste Method , 2) Soil Water Suspension Method and 3) Soil 0.01 M CaCl2 suspension Method. Which of these methods is most accurate, and gives highly reproducible results and why

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
