What is the mass of the 3.7 mol pbo2
explain

Find the molar mass first
pb=207.2 and O=16
molar mass=(207.2∗1)+(16∗2)
                  =207.2+32  =239.2g/mol
mole= mass/molar mass
mass=mole∗molar mass
mass=3.7∗239.2
mass=885.0g

2positives of biotechnology: 1. plants have become more resistant to viruses and other communicable pests.2. with the of biotechnology, we have been able to produce better tasting fruits as well as vegetables.2 negatives of biotechnology: 1. biotechnology poses a number of environmental threats. genetically modifies crops often infect monarch butterflies and other insect species.2. viruses could combine with crops.
