What is the volume of a sample of liquid mercury that has a mass of 76.2g

D - density: 13.6 g/mL

m - mass: 76.5 g

V - volume: ???

d = m/V

V = m/d

V = 76.5/13,6

V = 5,625 mL

🙂

24 square root . i know im wrong but so what

energy required is 0.247kJ

Explanation:

The formula to use is Energy = nRdT;

Where n is number of mole

R is the molar gas constant

dT is the change in temperature

n = reacting mass of mercury / molar mass of mercury = 27.4/200.59 = 0.137

dT = final temperature - initial temperature = 376.20 - 158.30 = 217.90K

R = 8.314Jper mol per Kelvin

Energy = 0.137 x 8.314 x 217.90 = 247.12J

Energy in kJ= 247.12/1000= 0.247kJ

Hey there!

D = m / V

13.6 = 76.2 / V

V = 76.2 / 13.6

V = 5.602 mL

Units are all fine. No need of conversion.

Just Use the formula:

V = mass / density

V = 76.2 / 13.6 = 5.6 mL

* Density = 13.6 g/cm³

* Mass = 76.2 g

Volume = ?

D = m / V

13.6 = 76.2 / V

V = 76.2 / 13.6

V = 5.602 L

Volume is mass/density.

v=76.2g/14.184g/cms^3 (which I believe is the density of liquid mercury)

=5.37

its volume this is the answer because the mercury will turn into gas. gas has more volume because it takes up more space as it spreads.

53gm

Explanation:

The formula for density is:

[tex]density=\frac{mass}{volume}[/tex]

We know the density for mercury is 13.6 g/mL, and we know the mass of the sample is 53.8 g. Thus, we can plug these numbers into our equation and solve for volume.

The volume is unknown, so we can simply denote it as "x"

[tex]13.6 g/mL=\frac{53.8 g}{x}[/tex]

multiply both sides by x

[tex](x)(13.6 g/mL)=\frac{53.8 g}{x}(x)[/tex]

The x's cancel out on the right side and you are left with

[tex](x)(13.6 g/mL)=53.8 g[/tex]

From here, simply divide both sides of the equation by 13.6 g/mL and solve for x.

[tex]\frac{(x)13.6 g/mL}{13.6 g/mL}=\frac{53.8 g}{13.6 g/mL}[/tex]

[tex]x=3.955882353 mL[/tex]

Round to 3 significant figures, and your final answer is:

[tex]x=3.96 mL[/tex]

The volume of the sample of mercury was 3.96 mL.
