What is the frequency of infrared light of 1.0 × 10 m wavelength?

1 answer:

7 0

In order to find the answer you must plug in the information to the frequency equation, $c=fv$ . C is the speed of light, 3.0 x 10^8. By plugging in the information you receive a frequency of 3.0 x 10^7 hz.

At least three types of RNA are required for protein synthesis. Compare and contrast mRNA, rRNA, and tRNA by moving the descript

Vedmedyk [2.9K]

Explanation:

The difference among mRNA, tRNA and rRNA are:

mRNA: It carries DNA's protein building information from nucleus to the cytoplasm. It is also read as codons nucleotide triplet that indicate specific amino acids .

rRNA: The function of rRNA is to join amino acids to the peptide bonds.

tRNA: Delivers amino acids to the site of protein synthesis. It also has an anticodon that interact with specific codon of another nucleus.

The similarity among mRNA, rRNA and tRNA is that they all consists of ribonucleic acid and can exist outside the nucleus in eukaryotes.

A sample of an unknown gas effuses in 14.4 min. An equal volume of H2 in the same apparatus under the same conditions effuses in

Elena-2011 [213]

Answer:- molar mass of the unknown gas is 71.5 gram per mol.

Solution:- From Graham's law of effusion rates, the rate of effusion of a gas is inversely proportional to the square root of it's molar mass.

When we compare the effusion rates of two gases then the formula for Graham's law is:

$\frac{rate_1}{rate_2}=\sqrt{\frac{M_2}{M_1}}$

In this formula, V stands for volume and M stands for molar mass

Rate is volume effused per unit time. Since, the volumes are same, the formula could be written as:

$\frac{t_2}{t_1}=\sqrt{\frac{M_2}{M_1}}$

let's say in formula, subscript 1 is for hydrogen gas and 2 is for the unknown gas.

Molar mass of hydrogen is 2.02 grams per mol and the time taken to effuse it is 2.42 min. The time taken to effuse the unknown gas is 14.4 min and we are asked to calculate it's molar mass. let's plug in the values in the formula:

$\frac{14.4}{2.42}=\sqrt{\frac{M_2}{2.02}}$

$5.95=\sqrt{\frac{M_2}{2.02}}$

doing squares to both sides:

$35.4=\frac{M_2}{2.02}$

$M_2=35.4*2.02$

$M_2=71.5$

So, the molar mass of the unknown gas is 71.5 grams per mol.
