What is true of a solution of 1.0 M HCl(aq)? It contains 1.0 gram of HCl per 100 grams of water. It contains 1.0 gram of HCl per
2 answers:
Answer: It contains 1.0 mole of HCl per 1 liter of solution.
Explanation:
Molarity : It is defined as the number of moles of solute present in one liter of solution.
Formula used :
where,
n = moles of solute
= volume of solution in liter
Thus 1.0 M solution means the solution contain 1 mole in 1 liter of solution.

An image of the lewis structure of the compound OF2 is shown in the image attached.
A Lewis structure is a structure in which electron pairs on atoms are shown as dots. Sometimes shared electron pairs are shown by a horizontal straight line connecting the two atoms involved.
OF2 has no double bonds as shown in its structure. It is a compound containing only two O-F sigma bonds and no pi-bonds.
Answer:
Explanation:
Given parameters:
Mass of CuCl₂ = 2.50g
Mass of Al = 0.50g
Unknown:
Number of moles of CuCl₂ and Al = ?
Solution:
To solve this problem, we must understand that the number of moles is a fundamental property used in stoichiometry calculations.
Number of moles =
Molar mass of CuCl₂ = 63.6 + 2(35.5) = 134.5g/mole
Molar mass of Al = 26.98g/mole
Number of moles of CuCl₂ = = 0.019moles
Number of moles of Al = = 0.019moles
