Please check my work

3M solution of NaOH (1 liter worth)

molecular weight: 39.99
3 x 39.99= 119.97 grams dilute to 1000mL

3 M solution of HCl (1 L)

c1v1=c2v2
(12M)(?)= (3M)(1000mL)
?= 250 mL

please check thank you

    Yes,if you started with 12M of acid. YOu diluted to 1/4, which means you want one part acid, three parts water.

    Correct on the sodium hydroxide.
