Chemistry, please.?????

Question

1. mass- 345g

volume- 50 ml

density- ?

2. There is an unknown liquid. the mass was found to be .0045 kg. What volume would the liquid be if it was water at 4 degrees celsius?

I'm an honers nerd and i am finding that chem just is not my forte.

Answer 1

1..D = M/V = 345g / 50mL = 6.9g/mL Density.

2..0.0045kg x 1,000mL/kg = 4.5mL. of water (1g/mL at 4°C and 1atm. Pressure).

(The maximum Density and Minimum Volume parameters).

Answer 2

1.  345 g / 50 ml = 6.9 g/ml = 6.9 g/cc = 6.9 SG

2. if H2O is 1 g/ml then 0.0045 kg = 4.5 g = 4.5 ml

I'm a nerd too, but not exactly honorable

Answer 3

1. 345/50=6.9g/cm^3

1ml=1cm^3

2. water has a density of 1. its 4.5cm^3, or 4.5ml

make it a good day
