Answer:
1.71 × 10²¹ molecules
Explanation:
1 gram is equal to 1000 milligrams. The mass in grams corresponding to 500 mg is:
500 mg × (1 g / 1000 mg) = 0.500 g
The molar mass of ascorbic acid is 176.12 g/mol. The moles corresponding to 0.500 grams of ascorbic acid are:
0.500 g × (1 mol/ 176.12 g) = 0.00284 mol
In 1 mole of ascorbic acid, there are 6.02 × 10²³ molecules of ascorbic acid (Avogadro's number). The molecules in 0.00284 moles are:
0.00284 mol × (6.02 × 10²³ molecules/ 1 mol) = 1.71 × 10²¹ molecule
Answer: Id.k It weird I get confused too
Explanation:
Don't look or ask em
Answer:
0.085 (Ms)⁻¹
Explanation:
Half life = 12 s
is the initial concentration = 0.98 M
Half life expression for second order kinetic is:
So,

k = 0.085 (Ms)⁻¹
The rate constant for this reaction is <u>0.085 (Ms)⁻¹ .</u>
