Ablock of material has a volume of 2m^3. it has a mass of 1 ×10^4 kg. calculate the density of the material sample and express your results in g/cm^3 with appropriate scientific notation.

The answer to your question is: density = 5 g/cm³

Explanation:

Data

Volume = v = 2 m³

mass = m = 1 x 10⁴ kg

Density = d = ? g/cm³

Formula

density = mass/volume

Volume

                          1 m³  1 000 000 cm³

                          2 m³     x

                          x = (2 x 1 000 000) / 1

                         x = 2 000 000 cm³

Mass

                          1 kg   1000 g

                         1 x 10⁴ kg    x

                         x = (1 x 10⁴ x 1000) / 1

                         x = 10 000 000 g

density = (10 000 000) / 2 000 000

density = 5 g/cm³

i'm assuming that it's c.) red bank..

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
