Answer : The volume of a solution is,
Explanation : Given,
Mass of = 75.0 g
Molar mass of = 125 g/mole
Molarity = 3.5 mol/L
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the volume of a solution is,
Answer:
0.2762M Na+ in the solution
Explanation:
<em>2.07g of sodium iodide Is Dissolved In 50.ML Of A 0.30M...</em>
To solve this question we need to find the moles of sodium iodide, NaI, that are the same than the moles of sodium cation, Na+. The volume in liters of the solution is 0.050L. The molarity is:
<em>Moles NaI = Moles Na+ -Molar mass NaI: 149.89g/mol-</em>
2.07g NaI * (1mol / 149.89g) = 0.01381 moles NaI<em> = Moles Na+</em>
Molarity:
0.01381 moles Na+ / 0.0500L =
0.2762M Na+ in the solution
Rearrange the equation F = ma to solve for acceleration. You can change this formula around to solve for acceleration by dividing both sides by the mass, so: a = F/m. To find the acceleration, simply divide the force by the mass of the object being accelerated.
Hope this helps! :)
Answer:
Explanation:
given volume =5.3 litres
as we know that 1 litre =1 dm3
therefore 5.3 litres =5.3 dm3
now moles =given mass /molar mass
so mass =moles*molar mass
in order to find mass of carbon we need to find moles
therefore moles=given volume/standard volume standard volume at STP is 22.4 dm3
moles= 5.3/22.4
moles=0.236=0.24
now mass of carbon dioxide =moles*molar mass
mass = 0.24*44
mass=10.56kg
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. As you move down the table, every row adds an orbital.
