A microscope is used to magnify small objects that cannot be seen by the naked eye.what would you like to observe under the mircoscope and why?

If we convert the ounces to grams, there are approximately 283.495 grams of plant fertiliser

If nitrogen has 15% of this, all we have to do is divide this number by 100 to get the mass of 1% and multiply it by 15.

In the end, we end up with the mass of 42.5243 g

Hope I helped! xx
