What is the density of a 700 kg object with a volume of 649 m'? (Density: D™) 0.927 kg/m
3.4543 kg/m
1.079 kg/m
4.543 kg/m

There is a formula for this
d=m/V or p=m/V were d and p are the same thing d stands for density and p is the greek symbol rho so d=p they are the same thing. m stands for mass and V stands for volume

density = mass/Volume

d=700kg/649^3
=1.079 kg/m^3
( Don’t forget (^3) power of 3 because is important for the volume, for ex. m^3 cm^3 km^3 etc)
The answer is 1.079 kg/m^3

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
