1. The problem statement, all variables and given/known data A typical virus is a packet of protein and DNA (or RNA) and can be spherical in shape. The influenza A virus is a spherical virus that has a diameter of 85 nm. If the volume of saliva coughed onto you by your friend with the flu is 0.044 cm3 and 10−9 of that volume consists of viral particles, how many influenza viruses have just landed on you? 2. Relevant equations V=4/3(pi)(r^3) 3. The attempt at a solution Volume Influenza A = 4/3(pi)(42.5^3) = 321555 nm 4.4e^11/ 321555= 1368350 viruses landed What did I do wrong??
