Then there would be no acceleration if the velocity of the body is 0.
B is false.
not all carbon atoms have 6 neutrons. Carbon 13 for example has 7 neutrons
5.55 mol H2O
Explanation:
Water has a molar mass of 18.01528 g/mol. We can then calculate the number of moles of water as
100 g H20 × (1 mol H2O/18.01528 g H20)
= 5.55 mol H2O
