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.

5.65 g/ml

Step-by-step explanation:

The density of a substance is given by :-

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

Then, the density of substance will be :-

Since , the significant figures depend on the dividend .

Here the dividend (10.34) is hundredth unit.

Then, the

7

step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
