A100.0ml bubble of hot gases at 225 c and 1.80 atm escapes from an active volcano, what is the new volume of the bubble outside the volcano where the temperature is -25 c and the pressure is 0.80 atm

112.08 mL

From the question we are given;

thus, T1 = 498.15 K

                                     = 248.15 K

We are required to calculate the new volume of the gases;

Rearranging the formula;

Therefore;

Therefore, the new volume of the gas is 112.08 mL

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
