Answer:
13.687 grams of salt should be added
The total grams of 8.6% of brine solution produced is 852.687g
Explanation:
Solution mass= 962g
Salt= 6.2%
Water = 93.8%
962 gram of water is made up of:
902.356g ( due to vaporization which reduces mass)
= 902.356 - 123
= 779. 356g of water
59.644g of salt.
If we add x gram of salt for making brine solution up to 8.6%
=(59. 644g + x)g.of salt
% salt = Mass of Salt / Total mass of solution
= 0.086= 59.644 + x / 779.356 + 59.644 + x
= 59.644 + x / 839 + x
x= 13.687 g of salt
Grams of 8.6% brine solution will be:
Gram of water + total gram of salt added to form 8.6% brine solution.
= 779.356g +59.644g + 13.687g
= 852.687g
The total grams of 8.6% of brine solution produced is 852.687g
Strong Acid: dissolves and dissociates 100% to produce protons (H+) 1. seven strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, & HClO3 2. ... Weak Acid: dissolves but less than 100% dissociates to produce protons (H+) 1.
CHA is not an example of a molecule because there is no element represented by “A”
Answer:
40.7062 °C
Explanation:
Let the initial temperature = x °C
Boiling temperature of water = 100 °C
Using,
Q = m C ×ΔT
Where,
Q is the heat absorbed in the temperature change from x °C to 100 °C.
C gas is the specific heat of the water = 4.184 J/g °C
m is the mass of water
ΔT = (100 - x) °C
Given,
Mass = 2350 g
Q = 5.83 × 10⁵ J
Applying the values as:
Q = m C ×ΔT
5.83 × 10⁵ = 2350 × 4.184 × (100 - x)
<u>x, Initial temperature = 40.7062 °C </u>
