    Answer:

    m≈501.57 g

    Explanation:

    The density formula is:

    d=m/v

    Let’s rearrange the formula for m. m is being divided by v. The inverse of division is multiplication, so multiply both aides by v.

    d*v= m/v*v

    d*v=m

    The mass can be found by multiply the density and the volume.

    m=d*v

    The density is 1.06 grams per milliliter and the volume is 473.176 milliliters.

    d= 1.06 g/mL

    v= 473.176 mL

    Substitute the values into the formula.

    m= 1.06 g/mL * 473.176 mL

    Multiply. When multiplying, the mL will cancel out.

    m= 501.56656 g

    Let’s round to the nearest hundredth. The 6 in the thousandth place tells us to round the 6 to a 7 in the hundredth place.

    m ≈501.57 g

    The mass is about 501.57 grams.
