4. Calculate the number of carbon (C) atoms present in the 25 mL of sugar. Show all your workings
*​

of carbon

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.

mass of sugar=

To calculate the moles, we use the equation:

1 mole of sugar contains = of carbon

0.116 mole of sugar contains = of carbon

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
