Aluminum has a density of 2.70 gm/cm cubed. what is the mass of a peice of alluminum that has a volume of 100.00 cm cubed

density=2.70

volume=100

mass=density*volume

so,

2.7*100=270

mass is 270gram

270 g

Explanation:

The density of a substance tells you the mass of exactly one unit of volume of said substance.

100cm^3 x 2.70g/ 1cm^3= 270 g

i think it's 35 meters

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
