1.8 would be the top Sig fig
there's no picture here but I guess the answer would be:
considering the constant temperature, if you double the volume, the pressure would be halved.
like: volume is 2, pressure is 4
if 2×2, then:4÷2
The reactants have one C atom and four O and H atoms. Hope this helps :)
We know that density = mass /volume
so
mass=volume*density
volume=mass/density
so c is wrong
