Answer:
353kg
Explanation:
2000 x 0.1765 = 353kg
for every 1 cubic metre of helium there is 0.1765 kg of it
the balloon is holding 2,000 cubic metres of the helium.
That means that there are 2000 times of 0.1765kg of helium in the balloon
so you times 0.1765kg by 2000
<h3>The mass of the gas, on the other hand, does depend on volume. Cutting the volume in two cuts the mass in two. The mass in each section of the tank is one half the mass of the entire tank.</h3>
oh wait i wrote whole paragraphs let me fix this
okay so you mean this ?

Soap is the sodium or potassium salt of long chain of fatty acid. Fatty acids when treated with NaOH or KOH forms Soap. This process is called as Saponification. Examples of Soap are as follow,
1. Sodium Stearate C₁₇H₃₅COONa
2. Potassium Oleate C₁₇H₃₃COOK
Reaction of Soap with MgCl₂;
When Soap is treated with MgCl₂ or CaCl₂ it forms insoluble precipitate called S.C.U.M. The reactions with MgCl₂ are as follow,
2C₁₇H₃₅COONa + MgCl₂ --------> 2C₁₇H₃₅COOMg + 2 NaCl
2C₁₇H₃₃COOK + MgCl₂ --------> 2C₁₇H₃₅COOMg + 2 KCl
These reaction are often found in hard water. And this reaction decreases the effectiveness of soap.
