Question

(A) You are given a bottle that contains 4.59 cm3 of a metallic solid. The total mass of the bottle and solid is 35.66 g. The empty bottle weighs 14.23 g. What is the density of the solid? (B) mercury is traded by the "flask" a unit has a mass of 34.5 kg. What is the volume of a flask of mercury if the density of mercury is 13.5 g/ML? (C) a thief plans to steal a gold sphere with a radius of 28.9 cm from a museum. If the gold has a density of 19.3 g/cm3 what is the mass of the sphere? [the volume of sphere is V= (4/3)(3.14r3]

Answer 1

A) 4.67x10^3 kg m^-3

Answer 2

b) The initial mass is 34.5 kg = 3450g

Answer 3

How did you get that answer? Please explain it to me. :3

Answer 4

c) 600mL * (1.28g / mL) = 768g of battery acid

Answer 5

i am using a graphing calculator so the values might hve +-2 difference

Answer 6

Ohh. I understand. Thank you so much :) it's really great help.

Answer 7

that A

Answer 8

sorry about horrible writing

Answer 9

for b it is
The initial mass is 34.5 kg = 3450g

Volume = 3450g * (mL / 13.6g) = 253.68mL

Answer 10

and C is 600mL * (1.28g / mL) = 768g of battery acid

768g battery acid * (38.1g sulfuric acid / 100 battery acid) = 292.6g sulfuric acid

Answer 11

Haha. :) that's fine. Actually, we have the same writings. ^_^

Answer 12

ignore C i gave the wrong

Answer 13

By the way, what's the solution in letter B?

Answer 14

for b it is
The initial mass is 34.5 kg = 3450g

Volume = 3450g * (mL / 13.6g) = 253.68mL <------this

Answer 15

Thank you qazd. ^_^

Answer 16

thats the thief one
dont ask me from there i got it :)

Answer 17
