CAN SOMEONE HELP ME ASAP? The density of a certain material is such that it weighs 7 ounces for every 2.5 gallons of volume. Exp
lesya [120]

Answer: Density = 0.23 tons per cubic meter.

Step-by-step explanation:

Formula : Density=\dfrac{Mass(in \ ton)}{Volume (in\ m^3)}

1 ton = 32000 ounces

⇒ 1 ounce = 0.00003125 ton

⇒  7 ounces = 7(0.00003125)=  0.00021875 ton

1 gallon = 0.00378541 cubic meter

2.5 gallons = 0.009475 cubic meter

Density= \dfrac{0.00021875}{0.009475}\text{ tons per cubic meter}

\dfrac{21875}{94750}\text{ tons per cubic meter}\approx0.23\text{ tons per cubic meter}

Hence, Density = 0.23 tons per cubic meter.
