Areaction produced 37.5 l of oxygen gas at 307 k and 1.25 atm. how many moles of oxygen were produced? 0.538 mol, o2 1.86 mol, o2 3.22 mol, o2 7.56 mol o2

Answer : The correct option is, 1.86 moles

Solution :

using ideal gas equation,

where,

n = number of moles of gas  = ?

P = pressure of the gas = 1.25 atm

T = temperature of the gas = 307 K

R = gas constant = 0.0821 Latm/moleK

V = volume of gas = 37.5 L

Now put all the given values in the above equation, we get the moles of gas.

Therefore, the moles of oxygen produced were, 1.86 moles

im not exactly sure but i think its b!

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?
