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:
Explanation:
Hello!
In this case, since the force exerted by an object with a certain mass an acceleration is:
We can plug in the given mass of 12,000 kg and acceleration of 16 m/s^2 to obtain:
Best regards!
Radiation is the heat that travels directly to the earth
Based on the chemical equation, to balance the equation we use 2 as a coefficients of HCl on left hand side of reaction.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equation in which each entities are present in same amount on left side as well as on the right side of the chemical reaction.
Given chemical reaction is:
Zn + HCl → ZnCl₂ + H₂
Above reaction is not balanced equation as number of chlorine and hydrogen atoms are not same, so balanced equation will be:
Zn + 2HCl → ZnCl₂ + H₂
Hence we add 2 as a coefficient of HCl to balance the equation.
