N95 masks filter 95% of particles which are 1.18 x 10-5 inches or larger. Use this information to answer the following questions:

What size of water droplet in nm could pass through the N95 mask?

To find the size of water droplet in nanometers that could pass through the N95 mask, we need to convert inches to nanometers:

1 inch = 2.54 x 10^7 nanometers

So, 1.18 x 10^-5 inches in nanometers would be:

1.18 x 10^-5 x 2.54 x 10^7 = 299,720 nanometers

Therefore, a water droplet with a size of 299,720 nanometers or larger would be able to pass through the N95 mask.
