    If there will only be two data there will be two points that intersects when two circles are drawn, unlike what would happen if there were three or more. in three or more there will only be one point. hehehe. medyo magulo pero ganun yun. pag dalawa kasi dalawa ang point na pwedeng maging epicenter pag three kasi merong point na doon nagintersect lahat

    Hello!

    How many grams of Ca(OH)2 are necessary to prepare 450 mL of 2.25 M solution ?​

    We have the following data:

    m (solute mass) = ? (in grams)

    V (volume) = 450 mL → 0.45 L

    M (molarity) = 2.25 M (or mol/L)

    MM - Molar Mass of Ca(OH)2

    Ca = 1*(40.078u) = 40.078 u

    O = 2*(15.9994u) = 31.9988 u

    H = 2*(1.00794) = 2.01588 u

    ------------------------

    MM - Molar Mass of Ca(OH)2 = 40.078 u + 31.9988 u + 2.01588 u

    MM - Molar Mass of Ca(OH)2 = 74.09268 (≈ 74.09 g/mol)

    Now, we apply the data found to the formula of Molarity, let's see:

    M = \dfrac{m}{MM*V}

    m = M*MM*V

    m = 2.25\:\dfrac{mol\!\!\!\!\!\!\!\!\!\!\!\dfrac{\hspace{0.6cm}}{~}}{\diagup\!\!\!\!L} *74.09\:\dfrac{g}{mol\!\!\!\!\!\!\!\!\!\!\!\dfrac{\hspace{0.6cm}}{~}} *0.45\:\diagup\!\!\!\!L

    \boxed{\boxed{m \approx 75.01\:g}}\:\:\:\:\:\:\bf\gray{\checkmark}

    Will be necessary approximately 75.01 grams of Ca(OH)2

    The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.
