If a liquid has a density of 1200 g/l what is it’s density in charge/ml

-

Solution:- The given density is and it asks to convert it to .

Here, we could notice that only volume unit is changing ad we know that, 1 L = 1000 mL. Let's make the set up as:

=

So, the density is .

the correct answer is a

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
