50.4g of magnesium metal is added to a graduated cylinder containing 30ml of water. the water level rises to the 85ml mark, from this information, calculate the density of the magnesium metal?
Density= mass divided my volume. To get the volume of the magnesium (85-30) which is the volume of the magnesium and water - the volume of water only The mass is given so 50.4\55 the density 0.9 g per ml
