Consider two different solutions of the same UV-absorbing compound. Upon UV-analysis, Solution B gave an absorbance of 1.0 and S

olution A gave an absorbance of 0. 4 at the same wavelength. Solution B is higher in concentration than Solution A by what ratio (or percentage)

We have that the Concentration of solution B is 2.5 times more than solution A's concentration.

<h3>UV(Ultra violent) rays</h3>

Question Parameters:

Upon UV-analysis, Solution B gave an absorbance of 1.0

Solution A gave an absorbance of 0. 4

Generally the equation for the Absorbance    is mathematically given as

A = e*c*L

Therefore

For A solution  

0.4 = e*[cA]*L

For B solution  

1.0 = e*[cB]*L

Hence

\frac{0.4}{ 1} = \frac{[cA]}{ cB}

[cB] = 2.5 [cA]

Therefore

Concentration of solution B is 2.5 times more than solution A's concentration.

There are two isotopes of an unknown element, X-19 and X-21. The abundance of X-19 is 14.55%. A weighted average uses the percen
alekssr [168]

Answer:

2.765amu is the contribution of the X-19 isotope to the weighted average

Explanation:

The average molar mass is defined as the sum of the molar mass of each isotope times its abundance. For the unknown element X that has 2 isotopes the weighted average is defined as:

X = Mass X-19 * Abundance X-19 + MassX-21 * Abundance X-21

The contribution of the X-19 isotope is its mass (19.00 amu) times its abundance (14.55% = 0.1455). That is:

19.00amu * 0.1455 =

2.765amu is the contribution of the X-19 isotope to the weighted average

True [87]
Moles of NaN3 at STP  = volume of gas / 22.4 = 11.5/22.4 = 0.5mole. Massof NaN3 = moles of NaN3 x molecular weight = 0.5 x 65 = 32.5 grams.
