What is this piece?

Does anyone know what this piece is? I just bought this car, and I really love it, but it needs a lot of work. I am going to try and do what I can myself, but this little tube really concerns me. Thank you

Don't know. It is a molded rubber hose; probably a vacuum hose or oil breather hose. Take your photo to a Volvo repair shop or dealership. They will know what to call it and they probably have them in stock. It's obviously damaged and needs to be replaced to make the engine run smooth.
