The mass of 0.1200 L of benzene at 15° Celsius is 105.44 g.

FURTHER EXPLANATION

Density is a measure of how tightly packed the particles of a material are. The more tightly packed the particles, the greater the density and vice versa.  Density is also mostly defined as the amount of matter in a given volume or space. The amount of matter corresponds to its mass. Density is an intensive property of matter so it may be used to qualitatively identify an unknown substance.

To determine the mass of benzene, recall the definition of density:

density = \frac{mass}{volume}

Since the density and the volume of benzene are given, the mass can be calculated as follows:

mass = density \times volume

Before the given volume and density can be plugged into the equation, volume of benzene must first be converted to milliliters.

0.1200 \ L \times \frac{1000 \ mL}{1 \ L} = \boxed {120 \ mL}

Plugging into the equation for mass:

mass = 0.8787 \frac{g}{mL} \times 120 \ mL\\\\\boxed {mass = 105.444 \ g}

Use the density to convert volume into mass. 

since the density is in g/ml and the volume was given in Liters, we need to first convert the Liters into mililiters. just multiply by 1000 or move the decimal three times.

0.1200 Liters= 120.0 mL

120.0 mL (0.8787 grams/ 1 mL)= 105 grams

Balance each reaction and write its reaction quotient, Qc:(a) NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)
AleksAgata [21]

When we balance the given equation

NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

We will get

2NO₂Cl(g) ⇄ 2NO₂(g) + Cl₂(g)

Solution:

Balancing the given equation

NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

We have to balance the number of Cl

2NO₂Cl(g) ⇄ NO₂(g) + Cl₂(g)

We have to balance the number of N, O.

2NO₂Cl(g) ⇄ 2NO₂(g) + Cl₂(g)

We will get the balanced equation

2NO₂Cl(g) ⇄ 2NO₂(g) + Cl₂(g)

The reaction quotient will be

    Qc = [product] / [reactant]

     Qc ​= [NO₂(g) + Cl₂(g)] / [NO₂Cl(g)]

From Young's experiment, how does the frequency of light affect the number of lines observed?
Marina CMI [18]

Answer : (C) "Higher frequencies have larger spaces between lines".

Explanation:

In Young's experiment, the condition for constructive interference is given by :

dsin\theta=n\lambda.........(1)

n is order or number of lines observed

d is distance between slits

\theta is the angle between the path and the line from screen to the slits.

We also know that, c=\nu \lambda

or

\lambda=\dfrac{c}{\nu}

where,

c is the speed of light

\nu is frequency

\lambda is wavelength

So, equation (1) turns into

dsin\theta=n\dfrac{c}{\nu}

\nu=\dfrac{n\ c}{d\ sin\theta}

So,

\nu\propto n

or

Higher frequencies have larger spaces between line.

So, correct option is (C).
