Calculate the density of a sample of 1.00 mole of nh3 at 793mmhg and -9.00 c
xeze [42]

0.164 g/L is the density of a sample of 1.00 mole of NH_3 at 793mmhg and -9.00 degrees celcius.

<h3>What is density?</h3>

Density is the mass of a unit volume of a material substance. The formula for density is d = \frac{M}{V}, where d is density, M is mass, and V is volume.

Given data:

n = 1.00 mole

P=793 mm hg =1.04342 atm

T=-9.00 degree celcius = -9.00 + 273= 264 K

V=?

Using Ideal Gas Law equation:  

PV = n R T      

R = gas constant = 0.082057 L-atm/(mol-K)

(1.04342 atm)(V) = 5 X 0.082057 L-atm/(mol-K)  X 264 K

V = 103.67 Liters

Now calculate density:

Mole weight of NH_3 = 1.00 mole

So, the mass of NH_3 = 17.031 g

Density =  \frac{mass}{volume}  

Density =  \frac{17.031 g}{ 103.67 Liters}  

= 0.164 g/L

Hence, 0.164 g/L is the density of a sample of 1.00 mole of NH_3 at 793mmhg and -9.00 degrees celcius.

Anvisha [2.4K]

Answer:Ionic compounds form when positive and negative ions share electrons and form an ionic bond. ... The positive ion, called a cation, is listed first in an ionic compound formula, followed by the negative ion, called an anion. A balanced formula has a neutral electrical charge or net charge of zero.

Explanation:Simple ions:  

Perchlorate ClO4- IO3-

Chlorate ClO3- BrO3-
