Molarity =wt/M.wt * 1000/V
=> 1.77 = wt/180 * 1000/555
> wt = 1.77 * 180*555 /1000 = 176.823 g
Answer:
c
Explanation:
the oxygen in the air and water from the rain caused oxidation causing the copper wire to become tarnished.
The answers to you questions are 3,66 g of liquid water and 0,84 g of vapor.
Solution:1) Q₁ = mxCxΔT = 4,5 g x 2,108 J/°C x g x 10°C.
= 97,86 J heat required to warm the ice to 0°C.
2) = 4,5 g x 334 J/g. = 1503 J heat required to melt the ice to water at 0°C.
3) = 4,5 g x 4,184 J/°C x g x 100°C
= 1882,28 J heat required to warm the water from 0°C to 100°C. = 5400 J - 3483,14 J = 1916,86 J heat left to vaporize the water.
mass of the vapor= 1916,86 J ÷ 2257 J/g
= 0,84 g.
As temperature increases, pressure increases
