Hey, just wondering if i can get some verification with my answers. I need to find the number of molecules from a concentration that is 1.0x10^-22 M of AsCl3 in one mL. I divided my concentration by 1000mL to get it down to a concentration per mL and multiplied by avogrado's number. My answer is 0.06. However, I'm not sure that's right as the unit should be an integer. thoughts? i think I'm missing something.
