In preparing diluted solutions from concentrated solutions we can use the following formula
c1v1 = c2v2
c1 and v1 are the concentration and volume of the concentrated solution respectively
c2 and v2 are the concentrations and volume of the diluted solution respectively
Substituting these values ,
20 mL x 1.0 M = C x 60 mL
C = 0.33 M
The concentration of the resulting diluted solutions is 0.33 M
The answer to the question
Answer:
0.26 moles
Explanation:
Number of moles = mass/molar mass
Mass of SiO2 = 15.5g
Molar mass of SiO2 = 60.08g/mol
Number of moles = 15.5g/60.08g/mol
=0.257
= 0.26 moles
