To determine whether the amount of H2 in the lab is dangerous, we first need to know how much hydrogen gas is present in the room in units of percent by volume. For this particular problem, we cannot exactly determine since we do not know the total volume of the room. Hope this answers the question.

The density of water at 4 degrees Celsius is 1.00 g/cm cubed at unknown object has density of 7.9 g/cm cubed would you expect it
NNADVOKAT [17]

Answer:

The object will be sank

Explanation:

In this case the object is more dense than water.

Density is the relationship between a certain amount of mass of matter and the volume that is being occupied by it.

The object occupies more volume, so it occupies more mass.

As the mass from the object is higher, the object will be sank because the weight is higher than the weight from the liquid.

If the object has a lower density than the water, it will float on it.

An explanation of what will happen every time in a specific situation
kramer
The one that is being described above is what we call SCIENTIFIC LAW. Scientific law is what explains of what will happen every time in a certain situation. This is also different from scientific theory since scientific theory only gives an explanation to a group of happenings and this can still be modified. Hope this helps.
