anonymous · Answer

Mass$$M$$ is given 0.3mg
Density $$\rho$$ is given 0.5mg/mL
Use the relation
$$\rho=\frac{M}{V}$$
$$V=\frac{M}{\rho}$$
You will get your answer in mL

anonymous · Answer

The size of the syringe should be such that it can hold the volume of solution, that is volume of the syringe should be at least equal to the volume of the liquid.

Now a syringe is typically a cylinder, so unless they give u radius of syringe or it's height we can't really about it's size, but the volume of the syringe should be at least equal to the volume of the liquid
