Answer:
Coke, coal gas, gas carbon, ammonia liquor, and coal oil
Hey there!
Mass = 8.1 g
density = 1.65041 g/cm³
Volume = ?
Therefore:
D = m / V
<span>1.65041 = 8.1 / V
V = 8.1 / </span><span>1.65041 g
V = 4.907 cm</span>³
Yes, a solid has a fixed volume.
The formula of mechanical advantage in this situation is:
MA = Input Force ÷ Output Force
The input force is the 30N applied to a screwdriver while the output force is the 75N force to the lid.
So,
MA = 30N/75N
MA = 0.40
Hence the mechanical advantage of the screwdriver is 0.40.
Multiply the mass by the abundance and add each. Make sure to convert the percentage into a decimal. (49.946 * .043) + (51.941 * .838) + (52.941 * .095) + (53.939 * .024) = 51.99 round up using sig figs and the answer is c. 52.00 amu
