What volume of a 6.0m hcl solution is required to make 250.0 milliters of 1.5 m hcl

Answer : The volume for 6.0m HCl solution required = 62.5 ml

Solution : Given,

Initial concentration of HCl solution = 6.0m

Final concentration of HCl solution = 1.5m

Final volume of HCl solution = 250 ml

Initial volume of HCl solution = ?

Formula used for dilution is,

where,

= initial concentration

= final concentration

= initial volume

= final volume

Now put all the given values in above formula, we get the initial volume of HCl solution.

= 62.5 ml

Therefore, the volume for 6.0m HCl solution required = 62.5 ml

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
