Chemistry

DochEvi [55]3 years ago
5 0

Answer: The temperature is there to confuse you on purpose. Density changes with temp, but in these type of problems, they mean nothing

Explanation:

The formula for density is mass per unit of volume.

D=m/v

We dont have to do any conversions here so it boils down to division and multiplication.

0.785g/mL=mass/15mL\\0.785g/mL*15mL = mass\\=11.78 grams

Now for the second part:

0.785g/mL=15g/volume\\15g/0.785g/mL = volume\\=19.11mL
