Answer:
digital signal is the answer
Answer:
6.286 L.
Explanation:
Applying Charles Law,
V/T = V'/T'............................... Equation 1
Where V = Initial volume of the balloon, T = Initial Temperature of the balloon, V' = Final volume of the balloon, T' = Final Temperature of the balloon
make V' the subject of the equation
V' = VT'/T............................ Equation 2
Given: V = 6.50 L, T = 31 °C = (273+31) K = 304 K, T' = 21 °C = (273+21) K = 294 K
Substitute into equation 2
V' = 6.5(294)/304
V' = 6.286 L.
Hence the new volume in the balloon = 6.286 L.

Mass of H2O=2.01568g+15.9994g=18.01508gmol H2O.
Step 2: Multiply 1.24 mol H2O with the molecular mass. 1.24 mol H2O x 18.01508gmol H2O = 22.3 g H2O.
