Answer:
For 12.8 g there 0.807 × 10³ formula units.
Explanation:
Given data:
Mass of MgCl₂ = 12.8 g
Formula units for given mass = ?
Solution:
First of all we will calculate the number of moles.
Number of moles = mass/molar masss
Number of moles = 12.8 g/ 95.211 g/mol
Number of moles = 0.134 mol
According to the Avogadro number,
one moles = 6.022 × 10³ formula units
For 0.134 mol,
0.134 × 6.022 × 10³ formula units
0.807 × 10³ formula units
For 12.8 g there 0.807 × 10³ formula units.
Answer:
Explanation:
0.5678 G X GRAMS
KHC8H4O4 + NaOH = NaKC8H4O4 + H2O
1 MOL 1 MOL
0.5678G X 204G/MOL = 0.00278 MOL KHC8H4O4
0.00278 MOL KHC8H4O4 X 1 MOLE NaOH/1 MOLE KHC8H4O4=0.00278 MOL NaOH
0.00278 MOL NaOH/26.26ml=0.106 molar
