Vitellium (Vi) has the following composition:
Dvinal [7]
Answer is: <span>C.)It will be closer to the mass of Vi–193.
</span><span>Average atomic mass of vitellium =
Ar(Vi-188) </span>· ω(Vi-188) + Ar(Vi-191) · ω(Vi-191) + Ar(Vu-193) · ω(Vi-193).
Average atomic mass of vitellium = 
187.9122 amu · 0,10861 + 190.9047 amu · 0,12428 + 192.8938 amu · 0,76711.
Average atomic mass of vitellium = 20,409 + 23,725 + 147,970.
Average atomic mass of vitellium = 192,104.

A cube of an unknown metal is 1.25 inches on each side and has a mass of 128.3741 g. What is its' density?
Mademuasel [1]
Hey there!

To find the density of an object, you must use this formula:
Density=Mass/Volume

Knowing that your mass is 128.3741, the only information you need left would be to find the volume of the cube.

Because the side length of the cube is given, you can multiply the length three times in order to find its volume:
1.25*1.25*1.25
=1.953125

Now that you have your volume and mass, divide the mass by the volume to find the density:
128.3741/1.953125
=65.7275392

Therefore, your density would be 65.7275392 grams per inches cubed.

Solution. Identify the concentration of the nye
Lana71 [14]

Answer:

12.5%

Explanation:

Given data:

Volume/Volume % = ?

Volume of solute = 25 mL

Volume of solution = 200 mL

Solution:

Formula:

v/v% = ( volume of solute / volume of solution ) × 100

by putting values,

v/v% = ( 25 mL / 200 mL)  × 100

v/v% = 0.125  × 100

v/v% = 12.5%
