how many militers of a 2.0M solution is required to prepare 50ml 0f a 0.3M solution

Use CV=CV or MV=MV to solve. First convert 50 mL to its equivalent in L, which is 0.050L and convert your answer to ml by multiplying your answer to by 10^3. After plugging in your values and rearranging your equation, the formula should look like V=(MV)/M=[().3M)(0.05L)]/(2.0M). Hope this helps.
