Answer:
0.93g/mL
Explanation:
Given parameters
Mass of wood = 3.16g
Initial volume of water = 20mL
Volume of water + wood = 23.4mL
Unknown:
Density of the wood = ?
Solution:
Density is the mass per volume of a substance.
It is mathematically expressed as;
Density =
Volume of wood = 23.4mL - 20mL = 3.4mL
So,
Density = = 0.93g/mL
Answer:
1.35 moles
Explanation:
Calculate how many
of potassium (K) are present in a sample of 8.12x10^23 atoms of K
6.02 X 10^23 atoms are 1 mole. how many 6.02 X 10^23 are in
8.12 X 10^23
divide 8.12 X 10^23 into sets of 6.02 X 10^23
(8.12 X 10^23)/(6.02 X 10^23) =1.35 moles
