I need help with percentage solutions in chemistry
I know that if i wanted 1% NaOH sol its 1g in 100ml or 10g 1000ml or
1m is 40g into 1000ml
How do I make solutions from liquids i.e hcl, h2s04 as they can refer to %
I know if I wanted a 0.5m sol from a 1m sol its a x2 dilution with water
what is concentrated hcl % how do I work this out
i'm i right in saying that mass of h2s04 is 98g, so 1m sol is a 9.8%
many thanks
