Correct conversion for determining weight of buffer?

[Violagirl]

I was going to see if someone could check my work to see if I went about solving this problem correctly?

 

Calculate the weight of HEPES you would use to make 100 mL of a 0.1 M buffer.

 

HEPES has a molecular weight of 238.3. So starting with 100 mL, I did the following:

 

100 mL X (1 L/1000 mL) x (0.1 moles/1 L) x (238.3 g/1 mole) = 2.38 g of HEPES.

 

Is this correct? Thanks for looking at this.

Looks fine to me.

Thank you for looking at this, I appreciate it!
