I am not sure how to properly use the scientific notation in this problem. I have attempted to solve it several different ways to no avail.
A house has a volume of 1.45 x 10(4)m(3). At 20.0° C and 740 mm Hg, the air fills the house. If the temperature and pressure increase to 35.0°C and 780 mm Hg, how much air must be drawn into the house to accommodate the change in volume of the air?
P1 x V(1)/T(1) = P(2) x V(2)/T(2))
V(2)= P(1) x V(1) x T(2)/ T(1) x P(2)
V(2) =740mm Hg x (1.45 x 10(4)m(3) x 308°K/ 293°K x 780mm Hg
V(2) = 330,484/228,540 = 1.44606 = 1.45
