here it is A new element has been discovered on planet Q-Blutonium.this planet is quite dense(47 g/cm squared) and very rare .It is worth 94.5 million dollars a gram.It cost the local labratory 2.2 million dollars to purchase a sample of the new element.What was the volume of the piece of Blutonium the lab purchased? Round your answer to the neareast ten-thousand of a cm squared (hint: volume = mass/density


THANKS SO MUCH FOR ANYONE THAT CAN DO IT

First figure the mass using a ratio. Then use the density to get volume...

Let M be the mass of the piece bought by the lab (in grams):

1 gram / 94.5 million = M grams / 2.2 million
M = 2.2 million / 94.5 million
M = 0.0232804233 grams

The density is 47 g/cm^3.

V = M/D
V = 0.0232804233 / 47
V = 0.000495328155 cm^3

The nearest ten thousandth would be:
0.0005 cm^3

Okay, if they spent 2.2 million dollars, we need to know hw much they bought (in grams). Use this equation:
x/(1 gram)=2.2/94.5 Solve for x (number fo grams purchased).

Once you know x, use the hint:
Volume = x/47

Good luck!
