The molar mass of O2 is 32g/mol. So the mol amount of these O2 is 56/32=2 mol. STP stands for the standard temperature and pressure which means the temperature is 0 ℃ and pressure is 100 kPa. And the molar volume of gas is 22.7 L/mol under STP. So the answer is 22.7*2=45.4 L
570/8.5=67.0 58... you only have to take the natural part, si the answer is 67 students
Answer:
The electrons where in motion
It should be 3.36 g / min but i m not sure
