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

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
