The volume occupied by 2.00 moles of nitrogen gas at the same temperature and pressure will be
0.500 moles = 11.2 Liters
what about 2 moles =? liters
by cross multiplication
= 11.2 liters x 2moles/ 0.500 moles = 44.8 liters
Answer:
6.50M
Explanation:
Molarity, M, is an unit of concentration widely used in analytical chemistry. Is defined as the ratio between the moles of solute (In this case, 5.46 moles) and liters of solution. To solve this question we must find the volume of the solution in liters in to find the molarity of the solution, as follows:
<em>Liters solution:</em>
840mL * (1L / 1000mL) = 0.840L
<em>Molarity:</em>
5.46moles / 0.840L
<h3>6.50M</h3>
Answer:
if its multiple, C and D, if not, C
Explanation:

Al atom has 13 protons, 13 electrons.
Mass number = number protons + number neutrons
27 = 13 + number neutrons,
number neutrons =27 - 13 = 14 neutrons .
Ion Al³⁺, lost 3 electrons.
So, in Al³⁺, 13-3=10 electrons.
So, ion Al³⁺ has 13 protons,14 neutrons, 10 electrons.
