Answer to Question #278435 in Chemistry for Khrvtin

Question

1.) If 202.5 g of mercury has a volume of 15cm³, what is the density of mercury?

2.)If the density of silver is 10.5g/cm³, what would be the mass of a silver whose volume is 9cm³?

Answer 1

Solution:

(1):

Density = Mass / Volume

Therefore,

Density of mercury = (202.5 g) / (15 cm³) = 13.5 g/cm³

Answer (1): Density of mercury is 13.5 g/cm³

(2):

Mass = Density × Volume

Therefore,

Mass of silver = (10.5 g/cm³) × (9 cm³) = 94.5 g

Answer (2): Mass of silver would be 94.5 grams
