If you place an item that is 2g/cm3 in a glass of water, will the object float or sink?

Phantasy [73]

It will sink in that glass of water.
as, it's density is more than density of water.

you might be known that the density of water is 1g/cm^2 and it's given that the density of the item is 2g/cm^2,
and
An object only floats in water if it's density is less than that of water so,
that item is going to sink.

Xianming runs a titration and collects, dries, and weighs the BaSO4(s) produced in the experiment. He reports a mass of 0.2989 g

Leto [7]

The question is incomplete, here is the complete question:

$Ba(OH)_2(aq.)+H_2SO_4(aq.)\rightarrow BaSO_4(s)+2H_2O(l)$

Xianming runs a titration and collects, dries, and weighs the $BaSO_4(s)$ produced in the experiment. He reports a mass of 0.2989 g go $BaSO_4$ Based on this, calculate the concentration of $Ba(OH)_2$ solution.
