Answer:
covalent bond- a chemical bond that is the sharing of electron pairs between atoms
First this is not Chemistry..
And to answer this you need to know simple formula :)
Wattage = Voltage * Ampere
So the answer is 480 Wattage
Answer:
20.3 % NaCl
Explanation:
Given data:
Mass of solute = 45.09 g
Mass of solvent = 174.9 g
Mass percent of solution = ?
Solution:
Mass of solution = 45.09 g + 174.9 g
Mass of solution = 220 g
The solute in 220 g is 45.09 g
220 g = 2.22 × 45.09
In 100 g solution amount of solute:
45.09 g/2.22 = 20.3 g
Thus m/m% = 20.3 % NaCl
Answer:
500 cubic centimeters of water
