Answer: option b) 1 dg
Explanation:
1) These are the different equivalences of those quantities:
a) 1 g = 100 cg ⇒ 1 cg = 0.01 g
b) 1 g = 10 dg ⇒ 1 dg = 0.1 g
c) 1 g = 1000 mg ⇒ 1 mg = 0.001 g
d) 1g = 10⁹ g ⇒ 1 ng = 10 ⁻⁹g
2) Now that you have all the masures in grams you can compare:
0.1g > 0.01g > 0.001g > 10 ⁻⁹g
3) So, the largest value is 0.1g which is 1 dg.
The pH of the finsl solution is equal to <u>2.93</u>
Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.
C₁ = 0.170 m
V₁ = 17 ml = 0.017 L
C₂ = 0.170 M
V₂ = 22 ml = 0.022 L
C₁V₁ =C₂V₂
0.170× 0.017 L = 2.89 × 10⁻³ ------------- HCl
0.170× 0.022 L = 3.74 × 10⁻³ ------------ NaOH
⇒ 3.74 × 10⁻³ - 2.89 × 10⁻³ = 0.85 × 10⁻³
⇒ 3 + log 0.85
⇒ 3 + -0.07
⇒ pH = <u>2.93</u>
The concentration of an solution is a degree of the amount of solute that has been dissolved in a given amount of solvent or solution. A focused solution is one which has a rather huge amount of dissolved solute.
