22.4 l of a gas at a temperature of 0°c are at a pressure of 2.0 atm. how many moles of gas are contained in the sample?

0.5 mol

1.0 mol

2.0 mol

3.0 mol

2 mol. When using pv=nrt, all conditions mentioned are standard except for pressure. Because the pressure is double, the mols also has to double from standard conditions. Therefore, instead of the standard 1 mol, it would be 2 mol.

Organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

Ithink the answer is c i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you
