# The Chemyst library To install chemyst run ```pip install chemyst``` ## Usage For P_total ```python # gas_laws stands for Pressure, Volume, Number of Moles, R is the ideal gas law constant, T is temperature from chemyst.gas_laws import P_total # Mixture of 3 gases lets say total_pressure = P_total([9.987, 2.33, 123.9]) print(total_pressure) # OUTPUT: 136.217 ``` Args: - pressure is the only argument to P_total - It is a list of the partial pressure of all the gases in a mixture ## Usage For partial_pressure ```python from chemyst.gas_laws import partial_pressure # Args: num_moles, ideal_gas_law, temp, volume, is_temp_kelvin=True pressureO2 = partial_pressure(2, 'atm', 31, 15.0, False) print(pressureO2) # OUTPUT: 13.2 ``` Args: - num_of_moles is the number of moles of the given gas - ideal_gas_law is the ideal gas law constant to use for the given pressure unit - if the pressure unit is atm - ideal_gas_law should be 'atm' - if the pressure unit is kpa - ideal_gas_law should be 'kpa' - if the pressure unit is mmHg - ideal_gas_law should be 'mmhg' - temp is the given temperature can be either Celsius or Kelvin - volume is the volume of the container - is_temp_kelvin determines whether the temperature should be converter to Kelvin or not - if the temperature is in celsius is_temp_kelvin should equal false ## Usage For the conversions module ```python from chemyst.conversions import moles_to_mass, mass_to_moles, atoms_to_grams, grams_to_atoms, ml_to_l, l_to_ml # Moles to mass OUTPUT: 512g moles_to_mass(16, 32) # Mass to moles OUTPUT: 16.0 mass_to_moles(512, 32) # Atoms to grams OUTPUT: 7.18e20 atoms_to_grams(1352, 32) # Grams to atoms OUTPUT: 1.88e24 grams_to_atoms(100, 32) # Mililiters to liters OUTPUT: 1 liter ml_to_l(1000) # Liters to mililiters OUTPUT: 1000ml l_to_ml(1) ``` Args: - moles_to_mass(num_moles, molar_mass) - num_moles is the number of moles to be converted to grams - molar_mass is the mass of the element in grams - for example O2 would have a molar mass of 32 - mass_to_moles(g_of_element, molar_mass) - g_of_element is the amount of grams which will be converted to moles - molar_mass is the mass of the element in grams - atoms_to_grams(num_atoms, molar_mass) - num_atoms is the number of atoms to be converted to grams - molar_mass is the mass of the element in grams - grams_to_atoms(g_of_element, molar_mass) - g_of_element is the amount of grams which will be converted to moles - molar_mass is the mass of the element in grams - ml_to_l(ml) - ml is the number of mililiters to convert into liters - l_to_ml(l) - l is the number of liters to convert into mililiters ## Usage for the molar module ### Molar and finding the moles The molar module gives the Molar amount (M) from the moles and volume of a solution ```python from chemyst.molar import molar, find_moles # Find the Molar amount of 3 moles of sugar in 5 liters of water molar(3, 5) # OUTPUT: 0.6M # Find the number of moles of sugar with the Volume and Moles of the same siolution find_moles(0.6, 5) # OUTPUT: 3 Moles Sugar ``` ## Usage For the yields module ### Theoretical yield The yields module is slightly different than the others the theoretical_yield() function takes 3 arguments: - actual_yield - the yield given in the equation - mole_ratio_top which is - From the balanced equation given, the number of moles of the wanted element - mole_ratio_bottom which likewise is - From the balanced equation given, the number of moles of the given element IMPORTANT: the theoretical_yield() function arguments MUST all be moles this can be easily achieved by using the ```moles_to_mass``` and ```mass_to_moles``` functions of ```chemyst.conversions``` ### Percent Yield the percent yield() function take 2 arguments - actual_yield - yield given in the equation - theoretical_yield - this yield can be calculated using the theoretical_yield() function IMPORTANT: the percent_yield() function arguments MUST all be grams this can be easily achieved by using the ```moles_to_mass``` and ```mass_to_moles``` functions of ```chemyst.conversions```
