Answer:
Carbon tetrachloride would be 2.2 fold heavier than water

Answer:
3.727x10^24 atoms.
Explanation:
When calculating how many molecules are in a compound or element, we refer to Avogardo's number.
Your equation will look like this: 1 mole/ 6.022x10^23 molecules (Avogardo's number).
Multiply 6.19 by Avogardo's number to get your answer.
Answer:To solve for time, divide the distance traveled by the rate. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours.
