An electron weighs 1/1836 atomic mass unit and, on the other hand, an alpha particle weighs 4 atomic mass unit.
<span>4 amu / (1/1836 amu) = 7344 </span>
<span>Therefore, an alpha particle is 7344 times heavier than an electron.
Hope this answers the question. Have a nice day.</span>
Because if they aren't properly included, it means that you are saying that the numbers can be anything, all reals.
Not including units is the same thing, if you don't properly lable the data table, you could be talking about anything.
Not giving a proper unit/variable is almost like giving someone permission to assume what you're talking about
Example : 30 ºC in <span>in kelvin
</span>
<span>ºC + 273.15
</span>
30 + 273.15 => 303.15 K
Answer:
8.90
Explanation:
Density = mass ÷ volume
D = 222.50 g ÷ 25.00
= 8.9
The density of the unknown metal is 8.90.
Hope that helps.
