About 300g - 320g for 10 litres powder mix , that what it is for mine yours maybe different does it not say on the label . I wouldn't use a rose ( water can rose ) a proper sprayer would be best but I think you can get something to fit a watering can which is like a sprayer.
How bad is the moss ? If its very bad and deep scarifying first and moss killing would be the way to go , then look into what causing the moss normally poor drainage. I

Surely there are instructions and/or guidelines on the container?
It's a place where beautiful isn't enough of a word....
I wouldn't go by the label on iron bags.
I also wouldn't use a watering can as it heavily overdoses the stuff. Plus... 300m2!!! Get a £20 sprayer.
If the moss is thick, you won't kill it effectively with iron.
Any signs of black later? You don't want to make it worse.
10 litres in a sprayer can be used with anything from 200-1000g soluble iron depending on the situation.
There's so much to consider here.
