There are 1.56 moles of solute present in a 2300 mL solution of 0.68M MgSO4.
<h3>How to calculate number of moles?</h3>
The number of moles of a substance can be calculated by using the following formula:
molarity = no. of moles / volume
According to this question, a volume of 2300 mL solution is contained in 0.68 M MgSO4. The number of moles is calculated as follows:
no of moles = 0.68M × 2.3
no. of moles = 1.56
Therefore, there are 1.56 moles of solute present in a 2300 mL solution of 0.68M MgSO4.

A. because you haven't released the object so therefor the potential gravity force applied becomes actual when released.
Answer is: new substance.
For example, synthesis chemical reaction: Ba + F₂ → BaF₂.
Synthesis reaction is a type of reaction in which multiple reactants combine to form a single product.
New substance, barium fluoride is formed, with different chemical and ohysical properties than reactants (barium and fluorine).
In barium fluoride, barium has oxidation number +2 and fluorine has oxidation number -1, so compound has neutral charge.
