The units of density are kg/m2. If the density of a liquid is 760.0 kg/m' what is the specific volume? a) 1.316 x 10 m2/kg b) 1.
zlopas [31]

Answer:

The correct answer is: 1.316 . 10⁻³ m³/kg.

Explanation:

The density (ρ) of a substance is the ratio of its <em>mass (m)</em> to its <em>volume (V)</em>. At constant temperature and pressure, its value is constant and it is an intrinsic property of materials. The units of density are kg/m³.

\rho = \frac{m}{V}

The specific volume (ν) of a substance is the ratio of its <em>mass</em> to its <em>volume</em>. We can see that it is the reciprocal of density and an intrinsic property of matter as well. Therefore, the units of specific volume are m³/kg.

\nu = \frac{V}{m}=\frac{1}{\rho }

Given we know the density of the liquid, we can use this relationship to find out its specific volume:

\nu =\frac{1}{\rho }=\frac{1}{760.0kg/m^{3} } =1.316 .10^{-3} m^{3} /kg

KATRIN_1 [288]

Answer:

2 NaOH + H2SO4 2 H2O + Na2SO4

How many grams of sodium sulfate will be formed if you start with 200.0

grams of sodium hydroxide and you have an excess of sulfuric acid?

355.3 grams of Na2SO4

200.0 g NaOH 1 mol NaOH 1 mol Na2SO4 142.1 g Na2SO4

40.00 g NaOH 2 mol NaOH 1 mol Na2SO4

= 355.3 g
