2. Given 90 ml of hydrogen gas collected at 27c, how milliliters will the hydrogen occupy
ase
MANY
at 42°C ?

94.5 ml

Step-by-step explanation:

it's the relation of PV = nRT

as pressure , moles and R are held constant

V1/V2 = T1/T2

where V is volume and T is temperature in "Kelvin"

V2 = V1 * T2 / T1

V2 = 90 * 315 / 300

the answer

b. they are parallel and will never intersect.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
