The answer I got was : 52.2
Answer:
cell membrane
Explanation:
Its definitely cell membrane, because the cell membrane is the outer layer, try looking up a animal cell chart, you'll see a black line around the cell. That black line is a cell membrane, the cell membrane covers over all its contents.
First, we need to get the number of moles of NH3:
no.of moles = mass of NH3 / molar mass
when we have the mass= 155g & the molar mass of NH3 = 14+(1x3) = 17 g/mol
∴ no.of moles = 155g/17mol/g
= 9.12 moles
∴ the heat (in Kj) = no.of moles of NH3 * (ΔHrxn/4moles NH3)
= 9.12 moles * (-906 / 4mol NH3)
= -2065.68 KJ
