Okay, so you need to start by finding the molar mass (grams in one mole) of nitrogen monoxide (NO).
N=14g
O=16g
So we know that NO has a molar mass of 30 grams, then just divide your given mass of 22.5 grams by the molar mass of 30 grams to find the number of molecules in your sample. The answer should be .75 molecules. Hope this helps!
Answer:
Example of a scientific question:
Does the angle of a ramp change the distance a toy car will travel?
Explanation:
Salt, silt, and clay particles
I would say compression or the absence of heat because heating a liquid makes it a gas<span />
