4. A light spring of constant k = 90.0 N/m is attached vertically to a table. A balloon (with empty mass 2.50 g) is filled with a mixture of helium (density = 0.179 kg/m³) and air (density = 1.29 kg/m³) to a volume of 4.00 m³ and is then connected to the spring, causing the spring to stretch. If the spring stretches by 1.0 cm, find the required density of the gas mixture, and find how much helium and air you need to produce that mixture.
