1) d = (703.55g-345.8g)/(225mL)

2) d= (6.12g)/(9L) * (1 L)/(1000mL)

and so on…

703.55-345.8= 357.75g

You then divide the mass by volume

357.75/225=1.403 g/mL

2.You convert liters into mililiters and kilograms into grams

9.00/1000=.009 mL 6.12/1000=.00612g

Then divide mass by volume again

.009/.00612=1.47g/mL

3. You find the volume of the rock by using the density formula: D=m/v

And I’m getting tired of solving these so I’ll let you do the rest lol.

All you have to worry about is converting them into the right measurements so that you can plug them into the formula

1 is easy. Subtract the mass of the flask from the total mass and divide by 225 mL.

2. convert kilograms to grams and divide by liters.

3. convert kg to g. ?cl = 4.85 g/cm^3 x 1cm^3/(x)g = answer

4. convert m to cm, multiply the dimensions and divide by grams (after converting kg to g)

5. convert .250L to mL, multiply g/ml by whatever you got, and then convert the result to centigrams

6. convert Liters to mL and multiply.
