pV = nRT
p = nRT/V
p= 1 x 0.08205 x 1000/ 2
p = 41.025 Pa
Edit: The unit should be atm instead of Pa, as pointed out by a nice human being.
It has a double C=C bond so that means it's unsaturated, but it can also be a cyclic compound with only simple C-C bonds
Number 2 is the mass of an electron
Answer: 40 + 2x14 + 6x16 = 164g/mole
54.3g x [1mole / 164g] = 0.331moles
355mL x 1L / 1000mL = 0.355L
molarity = 0.331moles / 0.355L =
00
