Answer:
The answer to your question is letter D. 2.02 g
Explanation:
Data
moles of Ne = 0.100
atomic mass of Neon = 20.18 g
Process
1.- Use proportions to find the answer
20.18 g of Ne ------------------ 1 mol of Ne
x ------------------ 0.1 moles
x = (0.1 x 20.18)/1
x = 2.018
2.- Consider the significant figures
0.100 has three significant figures so the answer must be 2.02 g
Answer:
There are multiple ways to check mass but I'll tell you one. Look below
Explanation:
One easy way of checking atomic mass is by adding protons and neutrons.
For example:
We have 5 protons and 4 neutrons.
5+4=9

<u>Answer:</u> The concentration of the diluted solution is 0.4788M
<u>Explanation:</u>
To calculate the concentration of the diluted solution, we use the following equation:
where,
are the molarity and volume of HCl solution
are the molarity and volume of the diluted HCl solution.
We are given:
Putting values in above equation, we get:
Hence, the concentration of the diluted solution is 0.4788M
