Donny Dont was asked what mass in kg a substance must have if its density is 3.00 kg/L and it takes up 12.0 gallons of volume. He correctly rearranged the equation for density, d=m/V, to solve for m: m=V*d, but what he put for his answer was “12.0 gal. * 3.00 kg / Liter = 36”. O n!! Donny Dont didn’t include any units after the number 36, and therefore his answer doesn’t really convey any information! He multiplied 12 * 3 correctly, but neglected to multiply or divide units. What units would his answer of 36 be in? Hint: it is a big jumbled mess of units. Ohhh n! Donny also failed to answer with the correct number of significant figures! How many sig figs SHOULD his answer contain?
