Answer:
150.1 mL
Explanation:
Step 1: Given data
- Density of benzene (ρ): 0.879 g/mL
- Mass of the sample of benzene (m): 131.9 g
- Volume of the sample of benzene (V): ?
Step 2: Calculate the volume of the sample of benzene
Density is an intrinsic property. It is equal to the quotient between the mass and the volume of the sample of benzene.
ρ = m/V
V = m/ρ
V = 131.9 g/(0.879 g/mL)
V = 150.1 mL
Answer:
A. Soil erosion will increase.
Answer:
there are 4 hydrogen so
A.the mass of Hydrogen in the reactant side of the equation above is 1×4=4 amu.
B.the mass of Hydrogen on the product side of the equation above =1×4=4 amu.

In pb (no3)2 there is:
Lead- 1 atom
Oxygen- 6 atoms
Nitrogen- 2
9 atoms in all
1.079 x 10⁹ km/h

2.998 x 10⁸ m/s has been known as the speed of light.
Let us convert the unit m/s to km/hour.
Change in unit length:
If 1 km = 1,000 cm, then 
Change in unit time:
If
, then 
The Process:



Remember, we must write the results in scientific notation, i.e.,

Thus the result of unit conversion is
