This
can be solved using Dalton's Law of Partial pressures. This law states that the
total pressure exerted by a gas mixture is equal to the sum of the partial
pressure of each gas in the mixture as if it exist alone in a container. In
order to solve, we need the partial pressures of the gases given. Calculations
are as follows:<span>
P = P1 + P2 + P3
<span>P = (0.08206 atm.L/mol.K)( 298.15
K)/1.50) x (0.158 mole + 0.09 mol + 0.044 mol) = <span>4.76
atm</span></span></span>
Answer:
Molarity = 12 M
Explanation:
Given data:
Molarity of solution = ?
Number of moles of NaCl = 3.0 mol
Volume of solution = 250 mL (250/1000 = 0.25 L)
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Molarity = 3.0 mol / 0.25 L
Molarity = 12 M
Explanation:
d.NaCl is a neutral salt, not an acid
In simple terms a force is what makes anything do move or stay still. Some forces are contact forces and some are non contact. Hope this helps.
