The answer should be C. Technology is the application of the knowledge gained by science.
The answer is 315.59095 grams :)
I would say b is the correct answer
Answer:
c
Explanation:
kinetic energy can be calculated using the formula
=1/2*mass*velocity or speed ^2
Answer:
The correct answer is D
<u>18.016 g</u>
<u></u>
Explanation:
Molecular Weight : It is the sum of atomic weights of each atoms present in the compound.
The molecular weught is measured in atomic mass.unit( amu) or simply"u"
This is calculated by using :
Molecular weight = number of atom x atomic mass of the atom
For H2O
Number of H atoms = 2
Number of O atom = 1
Molecular weight of H2O = 2(mass of H atom) + 1(mass of O atom)
Molecular weight = 2(1.00784) + 15.999
= 18.01558 u
= 18.016 u
