A block has a mass of 30g and dimensions of 1.5cm by 4.8cm by 2.3cm. Calculate the density (round to TWO sig figs).
1 answer:
Answer:
1.8g/cm³
Explanation:
Density is defined as the ratio of the mass of a substance and the space this subtance occupies. It is usually given in g/cm³.
The mass of the block is 30g.
The volume this mass occupies is 1.5cm × 4.8cm × 2.3cm = 16.56cm³.
The density is:
30g / 16.56cm³ =
<h3>1.8g/cm³</h3>
