If the density of a 45.0 cm3 block of wood is 0.65 g/ml what is the mass of the wood?
wlad13 [49]

Answer:

\boxed {\tt mass=29.25 \ grams}

Explanation:

The density formula is mass over volume.

d=\frac{m}{v}

Rearrange the formula for the mass, m. Multiply both sides of the formula by v.

d*v=\frac{m}{v}*v

d*v=m

Mass can be found by multiplying the density and volume. The density is 0.65 grams per milliliter and the volume is 45.0 cubic centimeters.

  • A cubic centimeter is equal to a milliliter.
  • Therefore, 45 cubic centimeters also equals 45 milliliters.

d= 0.65 \ g/mL\\v= 45 \ mL

Substitute the values into the formula.

0.65 \ g/mL * 45 \ mL=m

Multiply. Note the milliliters, or mL will cancel out.

0.65 \ g * 45=m

29.25 \ g=m

The mass of the wood is 29.25 grams.

What are 2 ways that convection currents in the oceans distribute the sun's energy?
dezoksy [38]

Answer:

When air in contact with the ocean is at a different temperature than the sea surface, heat transfer by conduction takes place. The ocean also absorbs and stores energy from the sun, and when precipitation falls, it releases heat energy into the atmosphere.

Hope it helps:)
