The maximum number of electrons in a single d subshell is:
son4ous [18]

10 electrons

Explanation:

The maximum number of electrons in a single d-subshell is 10 electrons.

The d-notation stands for an azimuthal quantum number or secondary quantum number.

This subshell can only accommodate a maximum of 10 electrons.

d- subshell has five orbitals

Each orbital is able to accommodate 2 electrons.

44.8% of a 250. mL acid solution is used in an experiment, what volume of acid (in mL) was used?
postnew [5]

Answer:

112 mL  

Explanation:

The formula for percent by volume is

\text{Percent by volume} = \dfrac{\text{Volume of solute}}{\text{Volume of solution}}\times 100 \, \%

If you have 250 mL of a solution that is 44.8 % v/v,

\begin{array}{rcl}44.8\, \% & = & \dfrac{\text{Volume of solute}}{\text{250 mL}}\times 100 \, \%\\\\44.8 \times \text{ 250 mL} & = & \text{Volume of solute} \times 100\\\text{Volume of solute} & = & \dfrac{44.8 \times 250\text{ mL}}{100}\\\\ & = & \textbf{112 mL}\\\end{array}
