Answer : The mass of vanadium(V) oxide will be 
Explanation : Given,
Number of atoms of
= 
Molar mass of
= 181.88 g/mole
In
, there are 2 atoms of vanadium and 5 atoms of oxygen.
First we have to determine the moles of
.
As,
number of vanadium atom present in 1 moles of 
So,
number of vanadium atom present in
moles of 
Now we have to determine the mass of
.


Therefore, the mass of vanadium(V) oxide will be 
Answer:
12 mL
Explanation:
Según la pregunta;
V / V% concentración del fármaco = 12%
volumen de la solución = 100 ml
De;
V / V% = volumen de fármaco / volumen de solución
volumen de fármaco = V / V% × volumen de solución
volumen de fármaco = 12/100 × 100
= 12 mL
