- If your front lawn is 21.0 feet wide and 20.0 feet long, and each square foot of lawn accumulates 1450 new snowflakes every minute, how much snow, in kilograms, accumulates on your lawn per hour? Assume an average snowflake has a mass of 2.00 mg Snow: _____________ kg/harrow_forwardif oil is placed in a large body of water, such as a lake or ocean it spreads out to form a surface monolayer one molecule thick. 0.10mL of oil will spread out over a roughly 40 square meters area. Given 1 L= 1000mL= 0.001 m^3. Volume = area x height. Given this information, calculate the average diameter of an oil molecule in nanometers. 1 nanometer= 10^-9 meters.arrow_forwardA chemist boils water and observes its boiling point is 100.C. The same chemist travels to Argentina to boil water and observes its boiling point remains the same. The chemist can say: A. boiling point is a physical property B. boiling point is a chemical property C. boiling point is a chemical and physical property D. Boiling point is not a physical propertyarrow_forward
