Answer:
The molarity of the solution is: 2,167 M.
Explanation:
Molarity is a concentration measure that expresses the moles of solute per liter of solution. In this case it is calculated with the simple rule of three:
3,6 L solution ------- 7,8 moles of MgCl2
1 L solution -----------x= (1 L solution x 7,8 moles of MgCl2)/3,6 L solution
x=2,167 moles of MgCl2 ---> <em>The solution is 2, 167 M</em>
Answer:
it's B
Explanation:
Oxygen is a reactant in combustion and the concentration of oxygen is higher in pure oxygenthan it is in air.
It is
A Venus flytrap closes on a fly.
C. A plant grows toward the sunlight.
E.Bright lights cause a baby to blink.
( i had a test have a good day )
M1V1 = M2V2
.200 (.025) = 1.60 X 10 -2 (V2)
V2 = .315 L
1.60 x 10-2 M in 315 mL
