The mass of a bottle filled with water is found to be 150 g. the mass of the empty bottle is 50 g and the external volume of the container is 125 `cm^(3)`. Find out the density of the material of the bottle.

The mass of a density bottle when it is filled with a liquid of density 3000 kg m^(-3) is 400 g and the mass of the bottle when it is filed with water is 200 g. The mass of the empty density bottle when it is filled with water is 200 g. The mass of the empty density bottle is "_____" g.

The mass of a density bottle when it is filled with a liquid of density 3000 kg m_(-3) is 400 g and the mass of the bottle when it is filled with water is 200 g. The mass of the empty density bottle is "__________" g.

When half of the total volume of an empty beaker of mass 100 g is filled with water, its mass is found to be 500 g and when the remaining volume of the beaker is filled with a liquid, its mass is found to be 1 kg. Calculate the density of the liquid.

An empty plastic bottle is kept and three holes are made in it at the same height from the bottom of the bottle. Bottle is now filled with water. Water stands leaking out 'from the holes. Do the different stream of water coming out of the holes fall at the same distance from the bottle? What conclusion do you draw ?
