What is the density of an object that has a volume of 34.2 cm^3 and a mass of 19.6 g? (a) 0.573 g/cm^3 (b) 1.74 g/cm^3 (c) 670 g
KengaRu [80]

Answer: The density of the object will be 0.573g/cm^3

Explanation:

Density is defined as the mass contained per unit volume.

Density=\frac{mass}{Volume}

Given : Mass of object = 19.6 grams

Volume of object= 34.2cm^3

Putting in the values we get:

Density=\frac{19.6g}{34.2cm^3}=0.573g/cm^3

Thus density of the object will be 0.573g/cm^3

synergistic interlayer and defect engineering in vs2 nanosheets toward efficient electrocatalytic hydrogen evolution reaction
Sever21 [200]

It is stated that VS2 nanosheets with abundant defects and an extended (001) interlayer spacing as large as 1.00 nm, which is a 74% expansion as compared to that (0.575 nm) of the pristine counterpart, may be produced using a straightforward one-pot solvothermal process.

For the electrocatalytic hydrogen evolution reaction (HER), the interlayer expanded VS2 nanosheets display exceptional kinetic metrics, including a low overpotential of 43 mV at a geometric current density of 10 mA cm2, a small Tafel slope of 36 mV dec1, and long-term stability of 60 h without any current fading. The performance is even comparable to that of the commercial Pt/C electrocatalyst and significantly better than that of the pure VS2 with a typical interlayer gap.
