I need help with these questions they are concerning density. This is general chemistry
. If you could help me with how to do these problems.
A rectangular block of lead has a mass of 175.3 g calculate the height of the block if the width is 2.25 cm and that length is 3.15 cm
An iron ore weighing 83.245 g was placed in a flask having a volume of 54.25 ml. The flask with the iron ore was then filled with water and weighed. The iron ore and water weighed 124.481 g. The density of water is 0.9976 G/ml. Calculate the density of the iron ore.
