600
Explanation:
there's 1 mole in every nitroglycerin
I think
Answer:
B. False
Explanation:
All the atoms of an element are not entirely the same no matter where they are found.
The phenomenon of isotopy brings a different perspective to the identity of an element.
- Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their various nuclei.
- Isotopes of an element have the same electrons but differ in their masses.
- They also differ in their chemical properties.
The molarity of the solution : 1.2 M
<h3>Further explanation</h3>
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
mass of NaCl=35 g
Volume of solution = 0.5 L
mol NaCl(MW=58.44 g/mol) :
The molarity :
