Oscar wants to bake bread.
To weigh the ingredients, he puts a bowl on a scale and zeroes it (so that the scale shows zero for the empty bowl).

Then, he starts adding rye flour into the same bowl.
This is what the scale shows.
Oscar needs in total 150 g of rye flour.
What weight of rye flour does he still need to add?
Which container will hold about 5 millilitres?
