The density of water is 1 g/ml, so my answer would be 155/1000 = 0.155 g. This means there are approximately 0.155 g of peanut butter in 1 ml of water.

In order to solve this problem, we need to first convert the mass of the water into grams. We know that there are 1000 ml in a liter, and that 1000 ml = 1 kg.
