Answer:
How many grams of copper (II) nitrate is formed
Answer:
b. 0.50 moles
Explanation:
To solve this problem we use <em>Avogadro's number</em> (6.023x10²³ atoms/mol).
By <u>dividing the number of atoms (or molecules) by that number</u>, we can calculate how many moles they represent.
- 3.01x10²³ atoms ÷ 6.023x10²³ atoms/mol = 0.50 moles
So the answer is option b. 0.50 moles.
Answer:
0.5mol/L
Explanation:
First, let us calculate the number of mole NaOH = 23 + 16 + 1 = 40g/mol
Mass of NaOH from the question = 30g
Number of mole = Mass /Molar Mass
Number of mole = 30/40 = 0.75mol
Volume = 1.5L
Active mass = mole/Volume
Active mass = 0.75mol/1.5L
Active mass = 0.5mol/L
