What volume of 0.100M sodium trioxonitrate (V) solution contains 5g of solute.
[Na = 23, N = 14, O = 16]
Answer Details
To calculate the volume of a solution, we need to use the formula:
moles of solute = concentration x volume
First, let's find the number of moles of sodium trioxonitrate (V) in 5g of the solute.
The molar mass of NaNO3 is:
Na = 23
N = 14
3 x O = 3 x 16 = 48
Molar mass = 23 + 14 + 48 = 85 g/mol
The number of moles of NaNO3 in 5g is:
moles = mass / molar mass
= 5 / 85
= 0.0588 moles
Now, we can use the formula above to find the volume of the solution:
moles of solute = concentration x volume
volume = moles of solute / concentration
volume = 0.0588 moles / 0.100 M
volume = 0.588 litres
Therefore, the correct answer is 0.588 litres of 0.100M sodium trioxonitrate (V) solution contains 5g of solute.
