Answer:
Molecules change speed based on temperature and state of matter. The warmer they are, the faster they move and vice versa. Solids are at a lower temperature than gases and liquids, which means the molecules are moving slower, and hold together better, also explaining why solids aren't malleable.
Answer:
0.00032 Grams of NaCl per 1 gram of the solution
Explanation:
It is not equal because it dose not obey the conservation of mass. 60+25= 85 not 75.
Answer:
number of molecules =9.03×10^23
Explanation:
use the equation
n=number of molecules /Av.constant
make number of Molecules become the subject of the formula by multplying Av.constant on both sides of the equation,
number of molecules=n×Av. constant ,where Av.constant is 6.02×10^23
number of molecules=1.5mol×6.02×10^23
=9.03×10^23
