Idont understand this i need to show work to. me.

a. m = Vd

b. 6.012g

Step-by-step explanation:

a.  you need to rearrange the equation so that you're solving for m. you can do so by multiplying both sides by V so you end up with

Vd = m or m = Vd (i prefer writing it this was purely cause it looks better)

b. now, you can plug in each value into the new equation so you get

5.01g/cm3 x 1.2 cm3 = m

from here you just multiply as normal

the answer is 5/14.

hope this .
