A design team is developing a prototype CO² cartridge for a manufacturer of rubber raft s. The is cartridge will allow a user to quickly inflate a raft . A typical raft is shown in the sketch. Assume a raft inflation pressure of 3 psi (this means that the absolute pressure is 3 psi greater than local atmospheric pressure). Estimate the volume of the raft and the mass of CO² in grams in the prototype cartridge.
