Question

Density is equal to mass divided by volume. The mass of a metal is 10.34 g. Its volume is 1.83 ml. Calculate its density. Use the proper number of significant figures.

Answer 1

Density = 10.34/1.83

Density = 5.65027

Significant figures is based on the lowest digit that was divided, which is to the hundredth unit.

In conclusion, the density is 5.65 g/ml^3

Answer 2

Answer: 5.65 g/ml

Explanation:

The density of a substance is given by :-

`\text{Density}=\frac{\text{Mass}}{\text{Volume}}`

Given : The mass of a metal is 10.34 g. Its volume is 1.83 ml.

Then, the density of substance will be :-

`\text{Density}=(10.34\ g)/(1.83\ ml)\\\\\Rightarrow\ \text{Density}= 5.65027322404\ g/ml`

Since , the significant figures depend on the dividend .

Here the dividend (10.34) is hundredth unit.

Then, the
`\text{Density}== 5.65027322404\approx5.65\ g/ml`
