Aliquid of mass 10 kg is enclosed in a cylinder of radius 1 m and length 5 m, what is the density of liquid? a) 0.63 kg/m3 b) 0.44 kg/m3 c) 0.54 kg/m3 d) 0.83 kg/m3

a)

Explanation:

Density is given by the expression , where m is the mass of the substance and V is the volume occupied by the substance.

As the problem says that the liquid is enclosed in a cylinder, you should find the volume of that cylinder that will be the same volume of the liquid, so:

For a cylinder the volume is given by V=

Replacing the values given, we have:

Replacing the values of m and V in the equation of density, we have:

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.

explanation:

- lead + phosphoric acid = hydrogen + lead(ii) phosphate
