(84.4C - 76.5C) / (5.03 C/m) = 1.5706 m
(1.5706 mol) / (1000 g CC14) X (25.00 G CC14) = 0.039265 mol
(5.00 g) / (0.039265 mol) = 127 g/mol
The answer is 5.5x10 to the power of 27.
6.02x10 to the power of 23 is how many particles are in one mole.
Therefore, if there are 922 moles then by cross-multiplying I multiplied 6.02x10 to the power of 23 with 922 and that's how I got the answer of 5.5x10 to the power of 27.
Answer:
Although this question is incomplete and i could not get the complete question online as well but to calculate the mass of the hydrogen peroxide, we use the formula below,
Density = mass/volume
But density =1.11g/ML
Volume = 118ML
Therefore mass of hydrogen peroxide = 1.11 ×118
= 130.98g
Answer:
A change which can be reversed
