The density of sodium is 0.97g/cmCUBIC. IF A SAMPLE OF SODIUM HAS A VOLUME OF 2.6CM CUBIC WHAT IS THE MASS OF THE SAMPLE

Alright, so the start point is the 2.6cm³. Next you use the density to find the amount in grams. The density can be written out as an identity which in this case would be 0.97gNa=1cm³Na. So you have this equation

2.6mL Na × \(\frac{0.97g Na}{1 mL}\) ≈ 2.5g Na

Remember that 1cm³=1mL and that all answers must follow the rules of significant figures and rounding.
