Hi , I basically need to make a 1 in 2 dilution of a solid material and i dont know how to do that. The material is in powder form so i need to make it liquid so that i can use it for a microbiology test in the lab. So this is why i need to dilute it and i have decided to make a 1 in 2 dilution of it with sterile water. But I do not understand how much of the powder i will be putting in to how much water.
if i have 0.10 g for example, how much would i need of this and how much of water to make a 1 in 2 dilution ?
Help needed quick
