EVERYDAY MANS ON THE BLOCK. Lol its 4. You got this from Mans Not Hot, didn't you? xD
It has 4 significant figures. If you see the Zero after the one decimal point you don’t count that and instead just started at 6
Ok the first one (C) for all of the answers is 6 and for the seconds one (Ca) the answers are 20
We calculate first the initial pressure of the gas.
P = nRT/V
= (0.215 g/mL)(1 mol/16 g)(0.0821 L.atm/mol K)(302K)
= 0.333 atm
Using the relationship between the pressure and temperature,
P1/T1 = P2/T2
Substituting the known values,
(0.333 atm) / (29 + 273) = P2/(950)
P2 = 1.05 atm
