Answer:
16.56 grams
Explanation:
The density can be found using the following formula:
If we rearrange the formula for m, the mass, we should multiply both sides by v.
The mass can be found by multiplying the density and the volume. The density is 2.76 grams per cubic centimeter. The volume is 6 cubic centimeters.
Substitute the values into the formula.
Multiply. When you multiply the 2 "cm^3" will cancel each other out.
The mass of the marble is 16.56 grams.
There are 1.93 x 10²⁴ particles
<h3>Further explanation</h3>Given
3.2 moles of Neon gas
Required
Number of particles
Solution
The mole is the number of particles(molecules, atoms, ions) contained in a substance
<em>1 mol = 6.02.10²³ particles </em>
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
So the number of particles for 3.2 moles :
N = 3.2 x 6.02.10²³
N = 1.93 x 10²⁴
or
we can describe it using Avogadro's number conversion factor
