<span>It is known that amu is equal to the molar mass of 1 mole of substance. Therefore,
</span>
Weight of one mole of uranium = 238 g/mol
The molar mass or molecular weight for U205 is 556 g/mol.
(238 x 2) + (16 x 5) = 556 g/mol
Answer:
18 liters
Explanation:
Step 1: Figure out what the formula and what you are dealing with.
- 25 degrees celcius is constant, so it is irrelevant for the mathmatical part.
- P1 = 1 atm
- P2 = 20 atm
- V1 = 360 liters
- V2 = trying to find
Note: remember the original equation is V1/P1 = V2/P2
- Step 2: Rearrange the equation to fit this problem, you should get...
V2 = V1 x P1 / P2
- Step 3: Fill our own numbers in. You should get...
360 L x 1 atm / 20 atm = 18 Liters (do the math)
- Answer = 18 Liters
- Remember to just follow the formula and fill it in with your own numbers.

Benzene
- Benzene has low density than the water itself of about 0.9 g/cm³
Low denisty object than the water usually <u>floats on the water</u>.
Another example: orange peel which floats on water has density of about 0.84 g/cm³
A part or aspect of something abstract, especially one that is essential or characteristic.
Given:
An experimental set-up where there are four test tubes containing different concentrations of hydrochloric acid, all at 25 degrees Celcius. All test tubes were added with 1 gram of Zn cube (at the same time).
The reaction which occurs at the fastest rate is the test tube where HCl concentration is greatest. The high concentration of HCl enhances the speed of the reaction.
