MH₂CO₃: (1g×2) + 12g + (16g×3) = 62 g/mol
1 mol --- 62g
0,8 mol -- X
X = 0,8×62
X = 49,6g
Answer:
HCl solution - H30+ and Cl ions. pH 3
NaCl - Na+ and Cl-. pH 7
Explanation:
a) HCl solution - the hydrogen ion combines with water molecule to form the hydronium molecule which is responsible for acidity. The chloride ion is also found in solution.
pH = -log [H+] = -log(10^-3) = 3
b) NaCl 10-3 g. The solid dissocates in water forming the Na+ and Cl- ions. None of these ions affect pH
The Hydrogen ion concentration of a pH 3.8 solution would be higher than that of a solution with a pH of 6.2. This is because since the pH scale measures the concentration of Hydrogen ions. We know that a pH range of less than 7 is considered acidic and greater than 7 is basic. If a solution is more acidic it would possess more hydrogen ions than if it weren't. In this case a pH value of 3.8 is more acidic than pH 6.2.

Hey there!
A MSDS is a Material Safety Data Sheet, and can be used to provide detailed and comprehensive information about the hazards of a certain product, such as medicine or chemicals.
