Answer:

3.01%

Related concentration units are parts per thousand (ppth), parts per million (ppm) and parts per billion (ppb). Parts per thousand is defined as follows:

ppth=massofsolutemassofsample×1000(15.3.4)

(15.3.4)ppth=massofsolutemassofsample×1000

There are similar definitions for parts per million and parts per billion:

ppm=massofsolutemassofsample×1,000,000(15.3.5)

(15.3.5)ppm=massofsolutemassofsample×1,000,000

and

ppb=massofsolutemassofsample×1,000,000,
