Answer:
the pressure = 1937mmhg using standered unit of volume
What mass of the following chemicals is needed to make the solutions indicated?
Answer:
271.6g
Explanation:
The mass of the chemicals need to make the needed solution can be derived by obtaining the number of moles first.
Given parameters:
Volume of solution = 1L
Molarity of HgCl₂ = 1M
number of moles of HgCl₂ = molarity of solution x volume
= 1 x 1
= 1 mole
From;
Mass of a substance = number of moles x molar mass;
we can find mass;
Molar mass of HgCl₂ = 200.6 + 2(35.5) = 271.6g/mol
Mass of the substance = 1 x 271.6 = 271.6g
