The mass percent of sugar in the solution is 1.225%
<u><em>calculation</em></u>
mass percent = [(mass of solute /mass of solution ) x 100]
mass of solute ( mass of a substance that dissolve in another substance)
= 2.45 g
mass of solution( mass of a substance that dissolves a solute) =200.0 g
Therefore mass percent = 2.45 g/200.0 g x 100 = 1.225% of sugar in solution
Answer:
60g/mol
Explanation:
By using nucleon numbers given on the periodic table, the mass of 1 mole of each element is:
C= 12g
H= 1g
O= 16g
Since molar mass is the sum of the masses of each element present in the compound,
Molar Mass (Mr) = 12+3(1)+12+16(2)+1 = 60g/mol
Answer:
option A
Explanation:
because acid comes from preparation of fossil fuel
Answer:
D
Explanation:
NO and O2 are both colourless gas. and its product is brown. thus when a brown gas is produced, you can say that NO and O2 reacted to form NO2
