Answer:
0.8078 Kg
Explanation:
Pressure of water = 0.15 MPa = 1.5 bar
At critical point of water ,temperature = 647 K=374°C
From the ideal gas equation
P×V= m×R×T
Let us assume volume = 1 m^3
1.5 x 105 x 1 = m x 287 x 647
m= 0.8078 kg
the fraction of mass of liquid at 25°C.
Answer:
NaOH
Explanation:
Look at charge Na has +1 charge and Ca has +2 charge after dissociation . Greater charge Stronger lattice. And as we need weak Lattice, so NaoH is stronger base than Ca(OH)2.

Answer:
78.6 lb/ft³
Step-by-step explanation:
Let's do this in steps.
1. Convert grams to pounds
D = (1.26 g/1 cm³) × (1 lb/454 g)
= 2.775 × 10⁻³ lb/cm³
2. Convert cubic centimetres to cubic feet
D = (2.775 × 10⁻³ lb/1 cm³) × (28 317cm³/1 ft³)
= 78.6 lb/ft³
