The tablet has a mass of 1.20 g and contains 700 mg of lithium carbonate.
kondaur [170]

Answer:

The right answer is "58.3%".

Explanation:

The given values are:

Mass of lithium carbonate,

= 700 mg

i.e.,

= 0.7 g

Mass of tablet,

= 1.20 g

Now,

The percentage of active ingredient will be:

=  \frac{Mass \ of lithium \ carbonate}{Mass \ of \ tablet}\times 100

On substituting the given values, we get

=  \frac{0.7}{1.20}\times 100

=  0.583\times 100

=  58.3%
