Ireally need with question one and two. i don’t remember how to do it and my notes aren’t making matters better

0.449 mole

We are given;

Volume of oxygen gas,V = 75.0 mL or 0.075 L

Pressure, P = 145 atm

Temperature, T = 22° C or 22 + 273 = 295 K

We are required to calculate the moles of Oxygen gas

We are going to use the ideal gas equation which states;

PV =nRT where, P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant,(0.082057 L atm/mol.K) and T is the temperature.

Therefore, to get n we use;

Therefore; the number of moles of Oxygen gas is 0.449 mole

35,410.99 torr

We are given

Initial Pressure of the gas, P1 = 30,400 torr

Initial temperature, T1 = 0°C or 273 K

Final temperature, T2 = 45°C or 318 K

We are required to find the final pressure, P1,

Therefore,

At varying temperature and pressure;

Thus;

Therefore; the new pressure in the container is 35,410.99 torr

possibly, yes.

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
