A fluоrescent dye hаs а mоlаr mass оf 560 gmathrm{g} mol−1mathrm{mol^{-1}}. Your lab protocol requires you to prepare 1×10−41 times 10^{-4} molmathrm{mol} of the dye in powder form before dissolving it. Your laboratory scale uses mgmathrm{mg} as a unit. Calculate the mass of dye (in mgmathrm{mg}) that must be weighed out to obtain 1×10−41 times 10^{-4} molmathrm{mol}.
