Physics An average family of four uses roughly 1200 L (about 300 gallons) of water per day ( 1 L = 1000 cm³). How much depth would a lake lose per year if it uniformly covered an area of 20 km² and supplied a local town with a population of 50000 people? Consider only population uses, and neglect evaporation and so on. Express your answer using one significant figure. d= 195| ΑΣΦ ? cm/y

1.1. Compute the density (in units of m) of an ideal gas under the following conditions: (a) At 0 °C and 760 Torr pressure (1 Torr=1 mmHg). This is called the Loschmidt number. (b) In a vacuum of 103 Torr at room temperature (20 °C). This number is a useful one for the experimentalist to know by heart (10 3 Torr 1 µ).
Estimate the number of molecules that make up Earth, assuming an average molecular mass of 30 g/mol. (Note there are on the order of 1024 objects per mole.)
One mole of atoms consists of 6.02 × 1023 individual atoms. If one mole of unicorn atoms were spread uniformly over the surface of a sphere the size of the Earth, approximately how many atoms would be found per square meter?

The ideal gas law states that a gas’s pressure P([kg]/[m][s]^2) depends upon its volume V ([m]^3), amount of substance n ([mol]), temperature T ([K]), and the ideal gas constant R. If the fundamental dimensions of ? is given by,R: [kg] [m]^2 [K]^−1 [mol]^−1 [s]^−2 obtain the ideal gas law by performing dimensional analysis. Properly define variables used
