Sagot :
Answer:
3.5g/ml
Explanation:
density=mass/volume
the mass of the mineral we have been given to be 35g
and it's volume is found by subtracting the initial volume from the final volume which is 35ml-25ml=10ml
Answer:
[tex]\boxed {\boxed {\sf 3.5 \ g/mL}}[/tex]
Explanation:
The density of an object is the mass per unit volume, so the formula is:
[tex]\rho= \frac {m}{v}[/tex]
We know the mass of the mineral sample is 35 grams.
We have to calculate the volume. The volume was found using water displacement. An amount of water was put in a graduated cylinder, then the object was dropped in. The volume is the difference between the final water level and the initial water level.
- v= final water - initial water
- v= 35 mL - 25 mL
- v= 10 mL
Now we know the mass and volume of the mineral sample.
- m= 35 g
- v= 10 mL
Substitute the values into the formula.
[tex]\rho= \frac{35 \ g}{10 \ mL}[/tex]
Divide.
[tex]\rho = 3.5 \ g/mL[/tex]
The density of the mineral sample is 3.5 grams per milliliter.
