The 6.023 * 10²³ molecule means 384.7 grams of Vitamin D.
<h3>What is a mole ?</h3>
A mole is a universal unit used to measure large number of atoms , molecules of an element.
one mole is equal to the Avogadro's Constant.
Mole is equal to the ratio of the mass of a compound to its molecular weight
It is given that Vitamin D is present
no. of molecule = 6.023 * 10²³
6.023 * 10²³ molecule constitutes of 1 mol
1 mole is equal to the molar mass of a compound/ element
Therefore 1 mole = 384.7grams of Vitamin D
and hence 6.023 * 10²³ molecule means 384.7 grams of Vitamin D.

Answer:
186.3g
Explanation:
4.5moles of K₂CO₃ is in 1000ml
? moles of K₂CO₃ is in 300 ml
(4.5 × 300)/ 1000 = 1.35 moles of K₂CO₃
1 mole of K₂CO₃ = (39 × 2) + 12 + (16 × 3) = 78 + 12 + 48 = 138g
1.35 moles of K₂CO₃ = ?
= (1.35 × 138)/1 = 186.3g
Answer: they will meet and make a biger wave then seperat
Explanation: When two or more waves meet, they interact with each other. The interaction of waves with other waves is called wave interference. Wave interference may occur when two waves that are traveling in opposite directions meet. The two waves pass through each other, and this affects their amplitude.
