    Answer:

    0.0025 moles H₂SO₄

    0.0050 moles H₂SO₄

    0.0100 moles H₂SO₄

    0.0150 moles H₂SO₄

    0.0200 moles H₂SO₄

    Explanation:

    The question is “How many MOLES…”

    Molarity, M, is an unit of concentration in chemistry defined as the ratio between moles of solute and liters of solution. To solve this question we must find the moles of 0.10M H₂SO₄ in the volumes:

    25.0mL:

    0.025L * (0.10mol / 1L) = 0.0025 moles H₂SO₄

    50.0mL:

    0.050L * (0.10mol / 1L) = 0.0050 moles H₂SO₄

    100.0mL:

    0.100L * (0.10mol / 1L) = 0.0100 moles H₂SO₄

    150.0mL:

    0.150L * (0.10mol / 1L) = 0.0150 moles H₂SO₄

    200.0mL:

    0.200L * (0.10mol / 1L) = 0.0200 moles H₂SO₄
