Its pH value signifies the variance from the neutral point of 7, where the farther you get from 7, the stronger the base or acid
A glow stick contains two chemicals and a suitable dye (sensitizer, or fluorophor). This creates an exothermic reaction. The chemicals inside the plastic tube are a mixture of the dye and diphenyl oxalate. The chemical in the glass vial is hydrogen peroxide.
Answer:
427.5g
Explanation:
Given parameters:
Number of moles = 4.5moles
Unknown:
Mass of MgCl₂ = ?
Solution:
To solve this problem;
Mass = number of moles x molar mass
Molar mass of MgCl₂ = 24 + 2(35.5) = 95g/mol
Mass = 4.5 x 95 = 427.5g
The math is set up like
35.6 ml * 2.7 g/ 1 ml
which will leave you with
96.12 g
