Answer:

50 MHz

Explanation:

The relation between frequency and wavelength is shown below as:

c=frequency\times Wavelength

c is the speed of light having value 3\times 10^8\ m/s

Given, Wavelength = 6 m

Thus, Frequency is:

Frequency=\frac{c}{Wavelength}

Frequency=\frac{3\times 10^8}{6}\ Hz

Frequency=50\times 10^{6}\ Hz

Also,

Also, 1 Hz = 10^{-6} MHz

So,<u> Frequency = 50 MHz.</u>

A 6.59-gram sample of a compound is dissolved in 250. grams of benzene. The freezing point of this solution is 1.02°C below that
iren2701 [21]

Answer:

30.12 g/m is the molar mass of the compound

Explanation:

Freezing point depression to solve this. The formula for the colligative property is:

ΔT = Kf . m

ΔT = T° freezing pure solvent - T° freezing solution

Kf = Cryoscopic constant

m = molality (mol/kg)

T° freezing pure benzene: 5.5°C

(5.5°C - 1.02°C) = 5.12 °C/m . m

4.48°C = 5.12 °C/m . m

4.48°C / 5.12 °C/m = m → 0.875 mol/kg

Mol = mass / molar mas

Molality = mol /kg

Let's find out the molar mass, with this equation:

(6.59 g / Molar mass)  / 0.250 kg = 0.875 mol/kg

6.59 g / molar mass = 0.875 mol/kg . 0.250 kg

6.59 g / molar mass = 0.21875 mol

6.59 g / 0.21875 mol = molar mass → 30.12 g/m

How many mm Hg are there in 2.27 atm?
vekshin1

Answer:

\huge\boxed{\sf 2.27\ atm = 1,725\ mm\ of\ Hg}

Explanation:

We know that:

1 atm = 760 mm of Hg (Standardly)

Multiply both sides by 2.27

2.27 atm = 760 * 2.27 mm of Hg

2.27 atm = 1,725 mm of Hg

\rule[225]{225}{2}

Hope this helped!

At a given temperature, the equilibrium constant for the formation of HI from H2 and I2 was found to be 29.9. Calculate the equi
evablogger [386]

Answer:

The correct answer is: K'= 0.033.

Explanation:

The formation of HI from H₂ and I₂ is given by:

H₂ + I₂ → 2 HI      K= 29.9

The decomposition of HI is the reverse reaction of the formation of HI:

2 HI → H₂ + I₂     K'

Thus, K' is the equilibrium constant for the reverse reaction of formation of HI. It is calculated as the reciprocal of the equilibrium constant of the forward reaction (K):

K' = 1/K = 1/(29.9)= 0.033

Therefore, the equilibrium constant for the decomposition of HI is K'= 0.033

The concentration of sugar in a soft drink is measured to be 10.5%. how many grams of sugar are in 125 g of the drink?
viva [34]
The grams  of the sugar in 125 g of the drink is calculated as below

%M/m) = mass of the solute (sugar)/  mass of the  solvent(drink) x100

let the mass  of the solute(sugar) be represented by y

convert % into fraction by dividing by 100 = 10.5/100

10.5/100 = y/125

by cross multiplication

100y =1312.5
divide both side by 100

y=13.125  grams
